I'm trying to distinguish the ride on the 500E. I've never driven a performance car before. I'm use to more 'touring' type rides from my 300E and 300SDL. THe car has Pirelli P8000's (which I think are outdated.. can't find references on Pirelli site) and I think I'm experiencing what Lee refers to as a 'sticky' tire. It's almost as if there is an adhesive on the tire that makes the noise of tape being pulled off (at low speeds). THe suspension is stiff so I feel the road 'feaures' more than with the other cars. Are these impressions accurate or should I have a silky smooth ride on the hiway?
