As a new owner (last four weeks), some good advice given earlier.I went to look at a car advertised on here that looked mint in the photos and (IMHO) was not mint when I looked at it. I travelled a long way to see it and was very disappointed. Found another fifty miles from home, 85k miles, good history and very good condition. Lots of receipts. Quite tidy under the bonnet which I always look for on adverts as a really dirty engine with loads of leaves and grime is not a good sign. I intend to give my a really good clean under the bonnet.
Don't rush, take your time and look at a few.
this is worth waiting for. I have gone from a 600bhp skyline to a near standard Z and I love it. I look forward to driving home from work on the days I take it in. On a sprint track I was not so excited, but that is not what I got the car for.
I am trying to convert all my friends to Z owners!
Awesome car. Bargain at the price.
Lastly, read all of the buying guides on here.
