What was the car Carly got in Transformers: Dark of the Moon?

I saw the new Transformers movie yesterday and I was wondering what car it was that Carly got? I know it's a Mercedes-Benz, costs $200,000, is silver and has doors that lift up but that's all I know. If you can tell me what car it is that would be great! Thanks!|||Mercedes Benz SLS AMG
