Edmunds' Expert Review

by the Edmunds Experts

Pros

Seductive style, quick folding retractable hardtop, commendable performance, ride and handling.

Cons

Heavy for a "sports car," limited cargo capacity.

What’s new

The V12 SL600 is added to the lineup, while the SL500 gets an industry-first seven-speed automatic transmission and an integrated "Keyless Go" keyfob.

Edmunds says

Between its elegant styling, impressive performance and cutting-edge technology, the SL roadster still reigns as the quintessential luxury drop top.

2004 Mercedes-Benz SL500 - UNRELIABLE

MMATLOCK, 12/19/2004

2004 Mercedes-Benz SL-Class SL500 2dr Convertible (5.0L 8cyl 7A)

Well, here we go. I bought my SL500 in March of '04 and immediately the top failed. It was recalled for brakes in June. Its transmission failed and had to be replaced in October. Rains came in November and the trunk/top leaked. The dealer assured me that this was an "isolated" incident. Unfortunately it happened to me. They had to replace the trunk hinges. I have never owned a …

Premium Price -Poor Quality?

Beautiful, Quality, 02/14/2009

2004 Mercedes-Benz SL-Class SL500 2dr Convertible (5.0L 8cyl 7A)

Beautiful car that gets a lot of looks. Fit and finish are right on par with what you would expect from a Mercedes. We have had many problems with the quality of this car: Broken interior panels, faulty anti-lock relay, faulty anti-lock brake pump, broken baffles inside gas tank (had to replace gas tank!). Now the ignition system has just failed. 53,250 miles, and many rented loaners. We …

2004 Mercedes-Benz SL-Class SL500 2dr Convertible (5.0L 8cyl 7A)

I LOVE THIS CAR. I HATE THIS CAR. EVERYTHING IS GREAT EXCEPT BUILD QUALITY AND RELIABILITY. DEALER REPLACED TRANSMISSION AT 1,300 MILES. BRAKES (Sensotronic) STILL DON'T WORK CORRECTLY. DEALER SERVICE IS APPALING. M/B CUSTOMER SERVICE (Montvale, NJ) IS RUDE AND UNHELPFUL. TRYING TO INVOKE MY RIGHTS UNDER NYS LEMON LAW SEEMS FUTILE. MY 4th M/B SL AND MY LAST.

TOTAL NIGHTMARE!!!

Matthew Garlough, 03/31/2016

2004 Mercedes-Benz SL-Class SL600 2dr Convertible (5.5L 12cyl Turbo 5A)

I purchased a pre-owned SL600 in spring 2013, and problems occurred almost immediately after leaving the lot. Dash displayed a TPMS issue, so I brought it back to find out that sensors for this were never installed but I could add them for $200 per tire. Less than 3 mo/3,000 miles later a hydraulic suspension hose burst lowering the car to the ground, and replacement for this was …
