What Owners are Saying About the 2004 Mercedes-Benz SL-Class

"Better than I expected"

"This car is a real joy to drive on long trips of short jaunts around town. Its been a real gem for me over the first 18 months, with no issues to report, other than the turbo "chirp" noise that was fixed after adding some stop squeak. I What's funny is this is the first real sports car I have owned that my wife also loves. I have owned Vettes, a 911 and Boxster S and she wasn't crazy about the ride for anything other than a quick trip to the store. But she loves this thing, going to Aspen, or shopping or down the the Springs and back. Everyone loves this car. I love the throaty sound. Its so much different than a typical Mercedes purrr and makes you really appreciate the ride more. Get this if: If you are looking for the best bang for your shopping dollar in the luxury performance arena. You love the balance of precision, power and cruise comfort. You don't mind people staring. You love to sometimes rocket to the speed limit. You are tired of ragtops and want something that feels like a sedan when the top is up."

"03 SL500"

"Beautiful car but buy a warranty and keep it. Batteries replaced 4 times, engine gaskets, leaks, glove box, locks, engine mounts,seat computers, windows always out of sync. This car is a rolling computer and something is always wrong with it even with regualr dealer service and low milage. It has alot of eletrical problems. i would buy this model again. Have had other Mercedes that were great for years. This is not one of them. Plan of 5k annual fixes plus routine maintenance."

"Wicked Fast!"

"I just bought a used SL65 AMG with less than 30K miles. My friends told me that MBZ's had quality issues, but I couldn't help myself. With over 600 hp it is quicker than my Z06 or 360 Ferrari. The styling is great, but too close to other MBZ's that are far less expensive. And then there are the quality issues. Not major ones, just a few quirky issues like electronics not fully working and brakes that squeak like a UPS truck. Not impossible, but for a car with an MSRP of over $200K, they are annoying. Also, the NAV system and the multiple menus for changing options are cumbersome to work with. But push the button on the gearshift to fire up that V-12 and the sound makes you overlook many of its shortcomings. WARNING: used values drop like a rock! Don't buy one new unless you can afford to take the huge hit."
