I got 3 still on the road that are 48 to 42 years old, I would be willing to bet that theese new ones want make it half that long, to much electronics. If Chevy would make a regular cab with a 5.3 and 4-6 speed tran with no frills for less than 30k they would sell them like hot cakes. If a guy like me can build one for less than 10k in an old model I know it can be done.
