I look at it as the value of the car keeps going up as being a rare factory sun roof and I could of put the money in the bank and collected interests on it at a rate of what? 1% a year I think and am better off with my car and the fun I had restoring it.
Nice Dart your friend has I bet he's proud of it and he should be.
Never get rich with your money in a bank. We have all ours invested but now being 71 I have to start withdrawing so much money a year from my Registered Retirement Saving Plans and then pay tax on it as income. That sucks.
