26. C3 ZL1

Year: 1969
Complex Says: Due to their extreme cost, only three '69 ZL1s were ever produced. They all had the fire-breathing 460hp 427ci (7.0L) aluminum V8, and suspension upgrades to match. For a long time, it was believed that only two examples were ever built, a white one and a yellow one, but Car & Driver tested a red one that hasn't been seen since. That's going to be a killer barn-find some day.
