2011 Cadillac STS

Looks/Style Ranked 2014 Chrysler 300 SRT Premium RWD better.
Front Seats Ranked 2011 Cadillac DTS Premium FWD worse.
"Prefer buckets to bench seats. "
Would Buy Ranked 2011 Cadillac DTS Premium FWD worse.
"I bought the STS over the DTS because Ive already had 2 STSs before and found them to be the perfect size. Cadillac should NEVER have discountinued the STS. I had trouble even finding one to buy. Was thrilled to find a 2010 STS V model with the Northstar v-8 engine. The CTSs were plentiful to find and buy, but are inferior quality and ride like a truck. The DTSs are also plentyful and are nice cars but are still too big. BRING BACK the STS model!! "
