great car but engine questions
 Engine is the only questions. 60,000 miles and a valve spring busted. this was in 2012 and cost $3,400 to fix. Now in December 2014 with 81,000 miles it's a leak in the timing cover, the oil pan, and the rack and pinion. Estimate cost to all is about $3,580. At some point you lose trust in a car. Everything else about the car has been great.
