...for a 2010 Lexus LS460 AWD? I have a 2009 Mercedes-Benz S550 4MATIC and would like to trade it in to my local Lexus dealership for a 2010 Lexus LS460 AWD. My Mercedes-Benz only has 3000 miles and it is just not the car I thought it was and and it's hard on my back. I'm just wondering what kind of a deal I can get and if it would be a straight-up trade or would the Lexus dealership owe me money on a trade?
