If you are purchasing a STS- V Check out the tire noize, almost 95 dbs. on a concrete freeway, hard to talk to a passanger or hear the radio at 65 mph, I took the runflats off and now it is a pleasure to drive.. Negociate a spair from the dealer and regular preformace tiers BEFORE you purchase. I put on Toyo tiers, no trade in they have a back room full of Perelli run flats that been taken off... GM said toooo bad so sad...I should haven test drove on the freeway.
Pencil holder, quieter ride, not easy to enter and exit. blind spots with the small mirrors
