^ Spot on mate.
If I was to move forward, then a clean, stock late model example - vspec II or varient would most likely be it.
I've had my quick cars, so still not so much looking for power at this stage.
However the clean, stock GTR's are hard to find as there arent many left. Thats where the search can be both, the fun (and also the frustrating) part and with the long wait and work required getting it as close to 'perfection' as possible in my eyes its still something I need to decide whether its worth the time and money.
On the flip side, with the R35 anyone can go and order one brand new from Nissan with little to no work required. And the depreciation / maintenance are the two pieces of the puzzle which have me second guessing them. Also the current unknown design faults which will show themselves in due time (For example with another model - the Nissan 350Z door lock actuators, window motors, convertible roof tears - etc).
Interesting discussions and obviously, personal preference will always play a major part in a decision or recommendation.
Thanks guys for your thoughts and insight.
