I had a P reg 1.4 SE on 128k miles, which I paid 500 quid for, but to be fair it was a high spec model with lots of factory fitted extras.
I should be purchasing an N reg 1.6 CL at the weekend for 350 quid. 10 months mot and 5 months tax. Unsure of mileage but with that much tax and test I'm not fussed because it's just gunna be adaily hack.
I have a P reg 2.8 VR6 Highline sitting on my front garden which I'll be putting on the road in September time when my insurance drops to a sensible price. (Approx 1200 squid)
Btw I'm only 18 and not really finding insurance a problem. Just under 500 quid for the 1.6 CL.
