Thanks for the feed back guys, especially Dan. You're right it's the cost of ownership that I'm considering. I'd love to say money isn't an issue, I can certainly afford to run the car with ease regardless of the cost but I don't want to be forking out thousands in servicing or repairs when things go wrong (touch wood the zed has just been wear and tear parts - brakes, tyres etc).
I've used Litchfield imports to get servicing prices for the GT-R, which whilst aren't cheap are at least a known entity at this point in time. Do these cars really need serviced every 6 months if Pre-2011?
Litchfield also offer warranties on the engine and drive train and I've seen people offer cars for sale on autotrader and on here with that as a positive selling point. These warranties range from £1k upwards. Now I know its a "pays your money, takes your chances" world but in reality what is the chance of an engine or drive train failure on a GT-R in comparison to any other car or even Porsche, Zed etc.
I think if I can purchase with a Litchfield warranty then this would give me a bit more peace of mind, but I'm wondering if it's actually worth keeping it going in the long run? I guess it's really just another form of insurance really?
May thanks again,
Jamie
