I had some answers that I previously had asked about a 69 Road Runner...

The fact that it is not numbers-matiching hurts the retail value, so your chances of getting the $25,000 back out of it in a hurry are slim. There are a couple of advantages, though. You can easily put a more modern drive train in it now, and not hurt the value in the least. That means you can get classic car looks combined with modern car handling, braking, performance and fuel economy. Sort of a 'best of both worlds' scenario. Done right, this may even bring the value of the car up some from the normal numbers-mismatched old car. One other thing to remember: They are not building any more of them, and each year the numbers remaining drops a little. What you have will always be a desirable body style of a desirable model. It would appear to be a pretty solid example, even if not the very prettiest. It has already passed the bottom of the depreciation curve and is climbing again, even if slowly. I would not do a full on 'restoration', but fix it with the goal of making it a good, solid, safe driver, and enjoy it. In 10 years, it may well be worth the more serious investment of restoration, and in the mean time, you have been having fun with the old girl.
