The SL55 puts track performance and handing capabilities into a comfortable street legal vehicle. That would be difficult to improve upon. I have owned other more exotic sports cars, some at twice the price, and the SL55 is the best to date. Anyone considering the SL65 should go to the SL55 instead. The added 800 pounds up front in the SL65 has a huge negative impact on handing, which is why the SL55 consistently beats on US and European tracks.
My SL55 has been the car I always wanted. It outperforms the 2 year old Porshe I turned, in all catagories. It is faster, corners better and much more comfortable. The hard top convertible gives you a quiet ride when up.I have had a few minor electronic problems that were fixed quickly I have the SL 65 sport package on mine. It is the same car as an SL65 without the extra 800 pounds in the motor and only 111 less H.P. This is the best production sports,luxury,Muscle car on the road. The downside, They charge you for all 3 cars.It beats almost everything. If you can afford a $145,000 car, This is the best car on the road.
