It is actually a LBZ. Check over everything like you would any other vehicle. I think that price is way high considering I paid $25k for mine new.Found a 2006 Duramax 3500 utility van w 75000 miles. It’s an early production 2006 and based on vin has LLY in it. Anything I should look for? Injector rates? Listed at $21k. Is this fair price? Thanks!
