If you can afford to buy new, go for it. It should get around 16. But the emission stuff will be a Pain in the... Personally I would buy an 06 or 07. The six speed tranny is very strong. As is the LBZ motor, no major problems to look out for. And yes, all duramax's have the allison tranny in them. As for the 05, if you like it go for it. The overheating problem is pretty easy to fix. There's a pretty good thread on it if you wana read up on it. cold air intake

Basically it can be solved with a simple hole in the air box like what "Hook 'em Horns" did to his.
