205s can suffer with electrical problems - mine is currently deciding not to start on occassion and I'm pretty sure it's a wiring issue that I need to trace. I'm not 100% confident with the reliability of mine at the moment and I've spent quite a bit of money on it over the years. Also the newest gti will now be 15 years old which is never a good thing from a reliability viewpoint. Unless you find one which has been fully restored/well maintained I think you could end up with two unreliable cars......
From a comfort viewpoint mines a bit creaky and rattly but I've upgraded the interior to take full leather from a 405 and it's really comfortable! Even as standard though they are pretty good.
Having said all that - go buy one. They are awesome fun!
