Suspension collapsed OSF.
Stereo completely packed up 2 months after the end of the warranty.
Various electrical glitches: horn jammed on, doors opening by themselves, stereo won't come on, aircon starting by itself.
Very poor driving position, steering wheel too far away, footwell very cramped, so that I hit brake/clutch at the same time.
Handling quite good, engine not bad, fuel so-so at 30-36mpg.
I wish I had kept the Saxo VTS - more comfortable, no problems, faster ,handles better, just more fun!
I got a 206 on a weekend's hire because I was thinking of buying one. I was glad I did because I suffered back pain from the poor seat and also had problems with the pedals being too close together.
It's a pity because it's a great looking little car, but it's a case of all fur coat and no knickers.
