Most of my bodyparts came from either RA designs or Venom. The venom boys are top class and have always treated me well, RA designs have supplied me with two splitters (smashed the first on on a grass mount not so long ago) and have always delivered promptly with the parts ariving in A1 condition. But then again ive not ever had to have a phone convosation wth them.
**EDIT**
Worst experences ive ever had was with bigboystoys. Took em 4months to deliver my strut braces (despite me canceling the order twice which they failed to process and charged me anyway) and when they did arive one had to be modded to fit, another went on easily and the third wont fit any model Mk2 VW unless you cut into the rear suspention beams (and im not doing that!)
