 My SLK55 is my first Mercedes-Benz.  It is by far the best vehicle I have ever owned.  I paid $1,000 over MSRP for it.  There was an eight  week wait for car.  I would definately do it again.  Its fuel Economy is great for a 355 hp V-8, EPA 16 / 22.  On my last tank I averaged 22.8 mpg.  The car is solid, yet rides great for a sports car.  I really like the AMG improvements over the 350.  It turns this car into a monster (with monster looks).
