Appreciation in value can take place without investing work, if you have a good car and a good price to start with. My '69, if I were to accept one of the many offers I've had for it, would now bring in over twice what it cost in 2003. Is that bad? Nope, it's a wise, and enjoyable, investment. After deducting cost of improvements I'd still end up well ahead.
