I just purchased my second car from World Motors. They were courteous, fast and efficient. No slimy salespeople here. Everyone is super professional. I got an amazing deal and I couldn't be happier. I paid about $10,000 less than Schumacher wanted for the same Mercedes. It is a small dealership so they don't have much to choose from. You need to be patient and wait for the right car. I just kept checking their website for inventory. They are my go-to people for used Mercedes in Scottsdale.
