Thats the Radio for 50K
 The car is one of the most sure footed cars I have ever driven.  I have two concerns - first there is a rattle in the back deck that the dealer fixed for a few day - it will be going back and second is the radio.  I can't believe the tinny distorted sound I get from the radio. I brought it back to the deal and was told it was working as designed and I can't upgrade it.  Looks like aftermarked to fix it.  Listen well to the radio before you buy.
