 I have been fortunate through the years to own a lot of premium sports cars and the SL was not one of them or even on my "Top 5" list.This time around, my "wants" changed, with comfort, amenities and room as a top priority. Because of the new SL's aluminum construction and bi-turbo V8, it was added as a possibility.After driving everything else out there, I finally drove a new SL.  It's agility, raw power and amenities were surprising, but the exterior lines seemed disjointed. UPDATE 11/2016This car has not disappointed me in any way. It has been problem free, and its performance limits are beyond anything I had expected. I replaced the wheel and tire package with aftermarket 20" wheels and non run flat tires. I also added the factory rear spoiler.  I hate run flat tires which come with the car, and the new wheels and spoiler give the car a more performance look. I have owned many nice cars in the past, but this car has definitely exceeded my expectations.    I bought the SL, added custom wheels and the rear factory spoiler and I am very pleased. These additions seem minor, but they changed the entire look of the car and I am pleased.
