Background: this is for my wife. She wants a Suburban, ESV or XL. I'm a DIY guy and can do most jobs myself. I typically buy something used, do a bunch of preventive maintenance, then enjoy it. I have $16k, but I'd prefer to spend $10-$12k so I have plenty left over for repairs/cosmetics. I expect to purchase something with over 150k miles. I'm not afraid of transmission rebuild. I have a savings for that. I am however, very concerned about AFM, because it's not something I know a lot about. I've been told I can avoid the entire AFM problem by purchasing a 6.2L... but is it true that the 6.2 is ONLY available in the Denali and Escalade? Would I be perfectly safe buying a 5.3L and spending $1500 on an AFM delete? Or is it significantly safer to buy a 6.2L right from the start. If you were in my position, what would you buy? Should I skip this generation entirely and put $10k down on a much newer truck, say something that costs $20k? Thanks!
