I am not saying your stuff is crap I dont know what you sell but how about repro parts of a decent quality most repro stuff I have seen is mostly crap, and not identical to the originals. I dont want to turn this into a bitch session but if your able to provide quality repro stuff you have me lining up to buy some stuff.
Things like Chrome moulds for the bumper bars, SL/Berlina eyebrow moulds for the tail lights, cerulean coloured interior parts like window winders, arm rests, all colours sunvisor retainer clips,door scuff plates, front seatbelt B pillar covers....
The list could go on and on with parts on most peoples wish lists but I have listed a few sought after parts just for starters.
cheers
