Still looking for a Suburban, 4x4. Some of the best deals Im finding have the 6.5 (2500s, 4x4). I know oil changes are more...a mechanic buddy of mine says "if the Turbo goes out, Im looking at $2-3000......? What are the chances...? We're just using it as a family hauler, maybe some fun off-road use, and we have two gas burners...Honda Accord, and Nissan Titan 2wd. Is the 6.5 really that more expensive to maintain, repair? And how likely is it a major component will fail (on average)? We're still looking at 94-99s in 4x4, and some 2500s... Any thoughts and info are greatly appreciated!
