They are great cars for what they are (reliable downsized RWD luxury cruisers), really the only bad aspects are the stupid F/M/J transverse torsion bar front ends and Iso-Clamped rear springs. You just can't expect to build a corner-carving Pro-Touring machine out of one like you can an A-body LOL.
