Non-Mopar car you wish you had purchased?

I had a chance at an 69 L88 427 4 speed Corvette in the early 70's. The owner somehow managed to strip the spark plug threads, one on the drivers side and two on the passengers side. I wasn't much into Chevrolet back then and I passed on it, my youngest brother finally put the money together and bought it for $2,000.00. I was called to help out with fixing it and told him I'll supervise, but he was going to do all of the work. He got the topside of the motor apart and took the heads to a machine shop to get the repaired. After about three years of it sitting around, he finally got it put back together. He drove it for a short time and go tired of getting tickets for being stupid with a 435 HP car. He sold it to someone he worked with and it hung around the area for a few years, trading hands multiple times. It was finally restored and sold at on of the big auctions for $80,000.00 according to my brother.
