Great car. Navigation should be DVD not CD based. Performance is exceptional for a luxury car. Would definitely recommend this car. Tire monitor warning system saved me twice before tire went completely flat. Important since no spare tire was supplied.Hard top convertible great improvement over my SL600 removable hard top. Keyless entry and start another of this cars great options. This car will not go at all in ice or snow. Can't wait to try the new SL65 or SLR.
