I suppose it comes down to whether you'd replace the car with something similar.
€7k gets you a lot of car these days. you're talking Audi TT, Mini Cooper, Peugeot 206cc, all much more modern cars than the FTO. I'd be surprised if you got over €4,500.
That said, the target buyer won't see that an average 95 tiptronic GS is worth €1k, they'll see pink paint
I can't see the car making €7k though.
It comes down to what the car is worth to you, and whether you fancy a change.
