Sold my pumped out 69 Vette that I never drove to pick up the Z to drive every day. I miss that Vette but when I analyse how much seat time I've had in the Z since I bought it, there's no way I can regret my decision. I'm over 80k on the Z and I probably would of only put 2k or 3k on the Vette. I should of kept both but than the Z would of needed to be outside the garage these last 6 years. Nah, made the right decision.
Sell it and move on. If you miss it get something better.
