I am from Melbourne in Australia and have a e46 99 cosmos schwartz 323i that I am using as a guinea pig.
I plan to replace the stock mirrors with carbon wrapped m6 auto folders, the stock bumpers with M-tech, the bonnet with a GTR carbon fibre, the boot with a csl carbon fibre and the woodgrain inserts with... you guessed it... carbon wrap. I have already done the pillars in a cheap carbon as a fill in (they were quite noticeably damaged when I bought the car) but I am also in the process of receiving new carbon wrap and clear coat wrap to do the job properly.
I started a project the involved bumper repair on a set of Pegasus bumpers that I got for 50 bucks. This was my original test run on doing things myself. The bumpers had some pretty significant damage but I have since repaired the front one and will begin on the rear one in a week or two. The rear is very damaged but I am confident with my chops in plastic welding and bogging now so am looking forward to finishing them off and putting them on my car until I have the funds to go the Mtech
