We've put a deposit down on a NSX this evening and all being well pick it up on Monday .
Made the decision after having the car checked out by Stratstone Honda today. They said that the car was nice and straight, and the engine good and strong. The only thing wrong really was that it looked like it had had some bad cosmetic work done, to possible respray stone chips/scratches. So with a little TLC some come back well.
So all I need to do now is sell the Supra so that the front of the house doesn't look like a car park for too long.
Thank you to everyone's help and advise on the forum.
