I bought a 2007 Mini Cooper from Ion last week and am very pleased with both the car and the buying experience.  Salem Mansoir, the general manager, is a very nice man and he made the transaction smooth and pleasant from start to finish. Unlike a lot of other used car salesmen, Salem is very low-key and straight-forward.  I felt no pressure to buy.  Salem is very knowledgeable about the cars he sells and he went out of his way to answer all my questions thoroughly.  He even showed me how much he paid for the car at auction!  I highly recommend Ion if you're looking to buy a quality car from a quality dealership.
