Your opinions please: what are the advantages/disadvantages between rubber and urethane body bushings ? Did a search and didn't find any topics comparing body bushings. I'd like to replace my 40 year old rubber mounts. Is this an area where you need the compliance of rubber or is it better to go with the longer-life urethane ? I'd like my car not to rattle more than it does now :) Thanks

The Poly's will give the car the feel of a more solid ride when you drive. Thus, less body roll, etc... But the ride quality (smooth cadillac-ness) will slightly decrease. You'll feel more of the road.
