I've owned a 81 K5 Jimmy and sold it so I'm looking at getting another now that I'm financially secure. My old K5 had a 350 /quadjet 350 tranny... headers, nothing special but now I'm looking to build a truck to keep for 20+ years. I like the CUCV but I know nothing about Diesel. I've read the posts here and I'm still in the dark. How much more expensive is a deisel to mantain than a gasoline engine? How expensive are repairs? Will the cash I save in gas and engine longevity be eaten up with mantainence costs and repairs? (assuming a new engine).
