Since this thread hasn't been updated in a long time let me bring you guys up to speed!
Shall start with the interior, its not 100% but a lot of minor things have been done !
Since the car was completely stripped out, managed to pull the carpet out and dye it BLACK. It was a dull grey and it was looking past it, slapped 10,000 bucks for a 5 litre can of Carpet dye and did it myself! WELL WORTH IT
Redid the hood lining to match as well, in a fabric very similar to the ones offered by BMW themselves
Upgraded the Stereo, not the fanciest but now running Infinity components in front and 6x9s at the back. Was lucky to source an adapter for the rear that converts the standard 4 inch speaker mounts to work with 6x9s. No need to cut and hack the parcel shelf!
The biggest step up for me was converting the Non original AC to factory spec digital climate control!
Since this is a UK car, it only came with a heater which was converted to AC locally. It never worked. So threw that rubbish away and got down all the bits required to convert to a fully functioning BMW ac system. This included the cooler box, the fans, the condenser, the compressor, receiver drier unit, piping, control panel and re did the wiring to work to factory specifications.
Got new chrome rings for the gauges
and some aluminum pedal covers.
Also got the M Tec II steering wheel restitched and re wrapped in leather. Keen eyes will notice I got the stitches in the M colors, was an official optional extra from BMW back in the day.
A friend was good enough to donate a genuine M gear knob which is slightly shorter than the standard one, which has improved shifts and shift feel immensely. Oh forgot to mention that I installed a short shift kit as well!
