i agree so much, all your missing is the 12 pack and can of corn breadmotoxxxman said:$300? are you nuts? what would that 300 be for? all you need is an oil pan gasket and rod bearings, and main bearings if you want to do them while there.
for rod bearings, main bearings, and an oil pan gasket you'd be shelling out about $100-$120.
and yes it is something you can do in your driveway with a jack and a pair of jackstands.
i'd say offer him $500-$600 for it. if the rod knock is really bad, you might want to find someone with a truck, and rent a tow dolly and tow it home on that. i usually pay about $65 for a tow dolly for 24 hours.
i wouldnt suggest driving it that far if the knock is fairly bad, it probably wouldnt last the whole trip.
