Only one in several hundred cars is an "investment". It has to be rare, desirable, original and in good condition. The rest are a hobby, especially if you are underwriting the restoration.

I do think Pontiacs are undervalued. But the market ebbs and flows, and the Mopar and GTO prices have softened over the last two years other than the rarest of the rare. It's hard to say what the next trend will be.
