Got any performance figures, how does it compare with the 210bhp?
I bought mine through Bonsaicars and 3.5 isn't a very good rating really. I would go for at least 4, obviously the cost will probably go up but it is worth it.
Service history is a good thing to look out for. And lastly be patient the right car will eventually come along I waited nearly 6 months and am chuffed with mine.
