Cars as investments are not a good way to go - they lose money. When you buy a car you should buy one that you want and that's being used for what you want to use it for. Racing, cruising, posing, garage queen, etc.
If it's stock you're after then more miles means less value. Modififications and upgrades increase the value of an older car as new, bigger breaks, new clutch, new tires, are also considered "rebuilds". If you instal lightweight bigger breaks on the car at 30K, like I did the brakes now are NEW, not 30,000mi. old. If you upgrade the engine with forged pistons and camshaft the new bearings, rings, etc, mean tbe engine is also lower miles than the car and slightly increase the value.
A buyer that wants smaller brakes, cast pistons, hot exhuast sills, etc. will say upgrades lower the value of the car. To him, they do, but to someone like me that wants a nice sounding, cool sill, big power, better handling car all my upgrades are equivalent in value to a much lower mileage car and most of us will buy the car for the way it drives and looks, not whatever the speedo says (they can be changed).
When I wrote off my 98 GTS, the insurance adjuster said that I'd upped the mileage 50% (19,000 - 29,000mi) and I'd devaued the car. I showed him the magazine feature article and my recent 1st place car show trophy and we adjusted the 'real' value up $9,000, not down. They increased the 'stock value' by $6,000 for the upgrades (sc, wheels, exhaust, etc.) and added another $1,000 for the upgraded electronics. The "book" value they started from was $45,000.
Get your monies worth, buy YOUR 'perfect car'.

, then you'll find far better choices IMO. If you're going to "invest in driving pleasure", then you'll be thrilled at your return.
