Lexus of Orlando Sold me a lemon Orlando Florida

I saw an SUV online and contact Lexus of Orlando.  I was told that the  vehicles they sell are in good condition and they would send cars to auction if they have major problems.  My husband rode the train to Winter Park and was taken to the dealership.  For the simple fact that we trusted what we were told over the phone, papers were signed purchasing the car before he even saw it.  He did not test drive it or listen to it because we just knew that a Lexus dealership wouldn't sell anything that wasn't in good repair.  We were told it was ready to go.  Neeedless to say this was a total mistake and a serious error in judgement trusting a salesman.  The car was driven home and immediately I contacted the dealership regarding a noise as a matter of fact it was the very next day.  Upon taking the vehicle to a mechanic it was discovered that the car has major issues.  It needs a timing chain and something about a turbo that will cost $3500 to repair which is half of the total cost of the car.  This has been an ongoing issue and we were totally deceived!!! We should have never trusted the saleman to begin with and did our own research and test driven the car.   A major major error in judgement.  This dealership doesn't care about its customers as long as they get their money.  They coud care less if they sell you a car that is in good working condition.  They were paid cash and this is a total disgrace to treat someone like this.  They don't stand by what they sell.
