Can I ask do you have any photos of the quad exhaust conversion from under neath, thanks, car looks great

Thanks!

As for the pictures, I am afraid no pictures from underneath the car. only from directly behind when it was installed back in 2012:

In essence: the back box at the left is in essence two back boxes unified in one single backbox casing (separate internals for the left and right part). The left part exits at the OEM cut out in bumper and diffuser , the right part is being extended behind the bumper to exit at the other side of the bumper / diffuser, where a new "hole" was created using a template.

Where did you get the bulbs from ?

^Both sets of LEDS (boot and indicator lightes) are from a UK company called Auto Lighting. For the ones in the rear light cluster you may want to start reading here: viewtopic.php?f=2&t=93757&start=9480#top

Coupe interior update

Further to the above update on the roadster's interior (new door cards, moving from aluminium interior panels to carbon leather interior panels, etc.) an update of the Coupe's interior was also due.

For the coupe it was "just" about the interior panels. The first owner had a slightly American taste; resulting in (as per this website: http://perso.numericable.fr/tonyz4c/index30si.html) the only LHD spacegrau coupe with black interior and fine wood interior panels in Europe (whereas at least 25 where produced for Northern America: http://perso.numericable.fr/tonyz4c/index30si.html).

Never mind its uniqueness (if it would have been ordered in bright pink it would also have been unique, but still would require action

), time to opt for a more sportier look by replacing the fine wooden panels by the aluminium ones I recently took out of the roadster.

Starting point

During the process

Result! (prior to cleaning)

Having torn a manual pre-fl roadster 's interior and an automatic coupe's interior apart within a few weeks: funny to see the little differences. Obviously in terms of some different parts, such as the upper plastic bits between the headrests and just below, slightly different connectors here and there and of course the bits related to the automatic shifting.

However, it also seems as if BMW cut down on some of the very small bits: a few washers less every here and there, one clipp less per side for the knee pads, etc., etc.

Anyway, during the interior swap I slightly ignored the exterior. Because of the lock down the coupe just sat for quite a while, resulting in it acquiring roughly 1/3 of the entire Sahara's dust:

Time for some TLC:

And following that a proper drive!
