You really are tempted by a return to the 370Z Tim: you mention it regularly. It's maybe time to go and get it done. £32K for a brand new quick coupe that handles brilliantly is very tempting.
That's not helpful, you should be exclaiming how expensive that is for something that's been around for 11 years and is past its sell by date with a coarse engine, cheap plastics and harsh suspension....
You're right though and for £3k down and £399/month that looks like a great deal if you like that kind of thing (which I do).
The timing is crap though, maybe next summer if the deals are still there.
In addition the car has a 3 or 4 year gap in its MOTs and between failing one at something like 30k miles and getting retested a month later it had done an additional 60k miles before returning to a more sensible mileage a year later. I'm sure its innocent but the car has clearly been laid up for a while at some point.
