I promised myself one before I was 30, brought it at 29, and owned it for almost 5 years, yet I rarely drove it. It always brought a smile to my face when I did though, but I was so anal with it, it was my weekend car, I only took it for drives if the weather was good, it never saw rain!
My misses was moaning it spent more time parked, so I reluctantly put it up for sale. Ironically, I saw it on Pistonheads last October, and it looked superb!
As you say, they are creeping up in value, especially the good ones, I definately regret selling it!
