It's been 20 years since I owned a g-body and I have the urge for another one. I'm just looking for something to commute 80 miles once or twice a week. Not looking for a hot rod, just a nice Cutlass to cruise. I have an all wheel drive van for winter so this is just a fair weather car. My question is if there's a significant difference in gas mileage between the 4.3 and the 5.0? Ideally I'd rather have the 8 but there a are a couple clean 6 cylinder cars nearby and I can get a nicer car for the money because of the motor. Yes, ideally I'd love to drive an 83 HO and I may have one again but that's not the purpose of this car. Just looking for a clean driver. Any thoughts?
