I'm looking to get a newer truck thise winter. I'm debating going with diesel or a gas vehicle. My dad doesn't like diesels (yes I am 35 and still listen to my father). I'm thinking he is remembering all the early 80's diesel junk that GM produced. I'm positive that he thinks diesels are unreliable. I don't have the same opinion so i'd like to get some opinions from you guys. I don't have very much experience with diesel vehicles, I'm more experienced with gas vehicles. Could you guys provide some input? 1. Reliabilty - Diesels vs. gas - Which vehicle has fewer repairs and which has more expensive repairs. 2. Mileage - Gas mileage. Does the better gas mileage of Diesel actually save any money when compared to other operating costs? 3. Life of truck - Which can I expect to get more miles out of ? 4. Cost - Are diesel trucks more expensive? Any other opinions would be appreciated.
