Handling was really poor when I bought it; this was due to a damaged anti-roll up-link bar (completely corroded and disconnected!) Also, it had a badly damaged strut (which meant I couldn't push this car around a round-a-bout without the body rolling 30 degrees!)
There is a sound of rattling over every bump; coming from either poorly attached number plates, or the stupid spare wheel (being under the car instead of securely inside the car).
There are also rattles from the manifold (possibly). This was a common problem on this particular car, from what I've seen in forums. It requires the manifold to be removed and spot welded, or a replacement manifold!
Generally, it's an OK car - that's it. I still own it, although I'm thinking of selling it even though I've spent a fortune getting the suspension corrected on it.
In a straight line, it does go well. I'm fairly impressed with it, by how quickly it seems to get from 0-60, and by how well it carries on pulling after I've reached over 100.
It has comfy seats. The driving position isn't that important to me, because you get used to your seat. I have driven worse!
Handling, even after the work on it, seems to be a real letdown. I've had mine for around 6 months and it still seems to feel like it is going to let go if I try to corner while racing. It is twitchy and I don't trust it. Maybe it won't let go and I should push it a little harder, but who wants to take risks like that if it means trashing your car? I've always had Vauxhall before now; Corsa SRi + GSi and also a Calibra 2l Sport, and both of those were excellent; you point it where you want it and it goes there - no questions asked! With this car, you edge it to where you want it, and cling on!
The interior is nice, and even though its only plastic, it is still well set out and all functions OK. I've heard of people having squeaky dashboard syndrome, but mine seems fine.
Outside, it is still just "OK". Mine is in mint condition, but apart from tiny GTi badges, it looks a bit like any other 206. The only things that really makes mine stand out are the nice metallic paint job, and the imported LEDs I've got on the back.
I would modify it more extensively, but at the end of the day it is still the same car underneath!
