BMW i8 - The bargain-buy "supercar" I wasn't expecting to own.

So - why go out and buy one of these?
Having sold
our Aston Martin DB7 after 9 years of ownership I decided to take a break
from the idea of owning a
weekend classic or "interesting" car.
For decades I have indulged in owning an extra car - as long as it
had done most of its depreciating before I bought it, was relatively
rare and not ridiculous
when it came to maintenance and parts. I would do my own
maintenance and servicing for the most part. However, with
ever increasing ownership costs and future
uncertainties perhaps now would be a good time to hold back and call
it a day.
I have always admired the
BMW i8, but had expected prices would remain well above what I would
be prepared to pay while I would still be in
the market for considering
such a car. However, while casually web-browsing cars
that would be tax exempt (just out of interest and to keep up to date
you understand), alongside all the
usual pre-1985 cars I was expecting to see, up popped the i8. Not only
that, but prices had now fallen into "Hmmmm, I could justify
spending that" territory.
After looking at various
examples and absolutely loving the driving experience I actually ended
up buying one locally from a small car sales dealer with a very good
reputation
(a
justified reputation
based
on
the subsequent service he has given us). The car we chose had the colour
combinations I prefer and the right balance of history, age,
condition,
mileage and price and a superb three year warranty. So there we have
it; I lasted just over four months without an "interesting
car".
This
time I have decided to keep things simple. No major modifications (the
DB7 was the last of those), just some very mild cosmetic tweeks to keep
my
eye and hand in.
I can't resist tinkering and I could see a number of small things I could
change and/or add to set our i8 apart from the rest.
Also, breaking from decades of tradition, given the complexities (and
my growing laziness) I decided not to do my own servicing. What is more
I decided to continue
its full BMW franchised dealer service history (some quotes revealed that
after
some polite negotiating, dealer prices were actually quite competitive).
Having said all that, it's still
good
to
see
that
the i8 sits nicely on the scissor lift in our garage; so perhaps I'll do the
odd
extra
oil
change after all....
What about the i8 ownership
experience? Well, so far it's been a revelation. I'm so glad we went
out to try one and then buy one - my wife also loves it.
Sure, there are much faster, louder, bigger engined and much
more expensive "proper" supercars out there, but for me that
does not detract at all from the i8 experience.
Here is a car that looks stunning, goes more than quickly enough, handles
beautifully, is comfortable and easy to drive and puts a smile on my
face every single time.
Add this to the very low RFL,
excellent economy (40+ mpg even if you "factor in"
charging), its rarity and a residual
value that can't
really fall that much lower given all
the above and where it is
now on the depreciation curve. I'm not even worried about the HV battery which
is still going strong and really only for extra boost dya to day.
Modifications.
To avoid insurance and/or warranty issues I have decided to keep changes to a bit of "gentle personalisation". The changes will be relatively few and relatively minor.
Wheels:
The wheels needed refinishing because
the wheel bolts had been previously tightened by a gorilla
on steroids and despite the very best efforts of a specialist
brought in, some damage occurred removing these bolts. The dealer paid for
the refurb and I went for solid black powder coat, because I know from experience
that
diamond cut
finishes
never
last
as well and today
just about every car you see has diamond cut wheels. They're just not special
these days.
I seriously considered a range of colours, but given the dark tones of the
car I decided that gloss black would be the best starting point for minor "embellishment".
The refurbishment
was done extremely well and included matching black alloy valves
and black weights. However, there was one complication.
All-black wheels are not actually my favourite on many cars due to the "big
black disc" effect where wheel/tyre boundary loses visual definition.
Now, like many i8s this one had blue accents. Many owners go out of their
way to hide/cover these blue accents, but instead, I decided to "Celebrate
the Blue".
To this end I spent some time doing very careful
measurements and trials and used blue wrap strips to highlight
the outer wheel rims to get the look I was after.
It was very fiddly to fit, but now it's done I actually prefer this look
to the originals (the small gaps line up with the spoke indents and also made
fitting easier).

Mirrors:
Well, I had spare wrap and so took the opportunity to add a
little more subtle blue highlighting. This is actually the first car
I have
applied
vinyl wrap
to.
Inner
sill covers:
A bit too much plastic, a bit too easily scratched and not special
enough for my tastes in a car like this, so I got creative to add a
bit of "bling".
This "bling" may change over time as I'm still unsure if
it's not too much. Will see
how
I
feel after living with it for a while.
I also took steps to reduce the chance of scuffing the plastic during
entry/exit.
The brushed stainless plates were
VW badged items from AliExpress. I cut out the VW centre,
widened
the hole, found a suitable small BMW badge and stretched a
copper washer to act
as the "i" surround which I painted the correct shade of blue. A lot
of fiddly work for such a small detail, but it keeps an old retiree occupied.

Rear spoiler:
I didn't really fancy the idea of fitting any of the variants of bits
of bodykit I've seen available for i8s. I
have seen a surprisingly
high proportion of i8s with
3rd party body kit fitted - side skirts
seem particularly popular and the Maxton range features heavily - no
surprise given the UK availability and reasonable cost.
Nothing wrong
with these additions, they're just not for me and my individual tastes.
However,
I did feel that the i8 would benefit aesthetically from something
to fill in
the "visual valley" between the "flying buttresses" at
the rear.
A rear spoiler would address this,
but after much internet searching I couldn't find a rear spoiler design
that I liked or looked as though it could have been OEM.
This presented the opportunity to create something which would make
our i8 truly unique and that really appealed to me (DIY vanity I suppose).
Unique among i8 spoilers was my
decision for a mounting location on the tailgate glass. This was for
very good
reason.
The glass of the i8 tailgate goes right to the back of the car.
This means the glass would
hit any spoiler fitted in the usual location across the rear.
The commercially
available examples have to extend far behind the rear of the car just
to allow the tailgate to open and to my eye this is a visual compromise
too far and also makes accessing the (admittedly tiny) boot space much more
awkward - at least it did on the car I've seen with one fitted.
To fix the spoiler I used both good quality ahesive and made covered
stainless clamps with rubber gaskets to securely fix the structure
to
the glass.
The end result isn't perfect and
I can see ways it could have followed the various lines and themes better,
but it was a compromise between what I would class as
"
ideal" and how
much time and money I was ultimately prepared to spend. There was also
the risk of spending an excess of my time and money and it all going
wrong.
Anyway, overall I'm very pleased with my efforts and most i8 novices
just assume it's how the car left the factory. Put it this way; I'm not
going to make another one.
Though it is heartening that a number of other owners have asked me to
make more.

Larger centre
display screen:
I don't understand why BMW fitted the 8.8" screen when there is more than enough
room for the 10.25" screen as used in the concurrent X5.
So I bought a cheap used X5 centre display screen and checked to see if it would
work
-
which
it did, perfectly. It's the same resolution, just bigger and brighter.
The difficult bit was getting the
larger screen to fit securely and neatly into the i8 as the mountings
and base are completely different.
I had to fabricate a new mount and then made trim pieces to cover the
bottom of the bigger screen. May sound simple, but was very fiddly indeed.
The result is superb; both bigger,
brighter and brings the cabin more up to date. Even the silver trim perfectly
matches the i8 vent surrounds.
Notice the view of the rear spoiler in the mirror.


Audio Upgrade:
I have tweaked the audio systems in most of the cars I've owned over the decades.
The Achilles Heel of the i8 Harman Kardon system is definitely the "subwoofer".
I am currently finalising a design for a custom
enclosure between the rear seats.
Simply
replacing the existing 6x9 driver and even adding extra
amplification would be terribly compromised if
using the existing space.
I will use a much higher quality (and powerful) round 8" dual coil sub
with its own compact amplifier.
Designing and trimming an enclosure based
around an amplified 8" sub
will be a huge challenge
as I want to
make it OEM in style, with OEM type trim and OEM quality.
Watch
this
space
-
just
don't expect quick results.
Other:
Actually for now that's all I've done apart from fitting a cordless phone charging
pad into the centre console cubby, etc. I may do more small tweeks
eventually.
