...what would it be DIESLor GAS? the truth is i'm not rich i cannot afford to buy a new car every 3 or 5years but i save enough money to buy my dream car or a real truck or SUV however we call it (G-WAGEN MERCEDES) due to the history of this truck it is a proven car, since they say i cannot out live this car well i plan to keep this car for as long as i live, for everyday everywhere and any purposes cause it is a real truck so my real question is should i get the new improve diesel engine or a gazoline one, i need to know which one will last or will meet my goal and which engine will still be a charm after years of usage.
and also what engine last longer V8 or V6

DIESEL is the way to go
