SL 600

I purchased my 2008 SL 600 new back in 2009; this was my first purchase of a performance luxury car. I just love everything about the car. The engine torque is amazing; when the twin turbocharger’s spool up the acceleration is scary fast. Cornering is flat and feels very secure. Interior noise is very low and luxurious. The overall build quality is second to none. I have owned the car for six years now and the only expense has been standard maintenance. The car did not have a single warranty repair during the warranty period or any repair required to date. I have owned the car for 8 years now and still no repairs, just standard maintenance. Slightly disappointing resale value, since only 110 units were sold in the US in 2008 you would think the car would hold resale value better.

While growing up heading into NYC, I would see the Sl 500's and told myself that some day I would own one. Went to get my wife an E 350, and this car was sitting along side it. Having MB handle the depreciation, it was still above my range, but what the heck. Yes, the Corvette and the BMW are faster, but what a way to get there. I don't need to feel every break in the pavement. The transmission is superb and gets out of the way. The engine is silent. The breaks keep it safe (the one thing I miss on my 335i). I don't know what people don't like about the Bose Stereo, and I am an audiophile. If you have the bucks, this is the car.

You’d have to be crazy.

Sometimes in life, we all roll the dice. I did because I really wanted an SL Class Mercedes. A pre-owned SL can be purchased for less than $20,000. Pretty enticing. So I took a chance and bought a stunning low mileage 2007 SL550 AMG. Dealer serviced since new with no accidents and in gorgeous cosmetic condition. Within 2 months the ABC system suffered a catastrophic failure. The transmission began to slip and hesitate between 1st and 2nd at low speed. Also, within a couple of weeks of gentle daily driving, the suspension has begun to make a nauseating creaking sound, and the roof has started rattling. At this point, without fixing the suspension creaking or roof rattles, it has cost over $7000 in ABC and drivetrain repairs within 60 days. You may be thinking, that I bought a lemon. Or, you might be thinking, this very well could happen to me. What I do know, if ya’ll are ichin’ for a beautiful pre-owned Mercedes SL, be warned. Go ahead, roll the dice.

I just bought this SL550 for my wife. What a beautiful car. She wanted a sports car and I would not let her drive my Z8 :-) This car is such a nice all around car. It had about 8K miles on it and is 2.5 years old and like another mentioned about 50% of initial MSRP. It was a certified MB so we got a additional 2 year 50K warranty on top of the existing warranty. The car is built like a tank and has plenty of power. It is no Z8 but a much better every day car and tourer and quite the luxury cruiser. We could have spent $60K on a new Corvette GS or the same on this TT&L and it was a no brainer.

Sports car morphs into luxury car

I have been lucky enough to have owned many sports cars. From the context of a “sports cars” perspective, my 2008 SL550 is not really a sports car. It is much too heavy and too focused on creature comforts. BUT, at 69 years young, I no longer yearn only for testosterone boiling speed, but perhaps for a tad more subtlety. This car is gorgeous. It can go far faster and harder than you would think based on its weight because it is a technological marvel. That’s really good, and also a bit daunting. This car borders on over-complicated, but it plays the role of luxury-sport car very well. It has two distinct personalities. It can be a boulevard cruiser whisking you to the opera, and it can be a blast in the open-air mountain twistees. It’s target demographic is not a sports car for a 20- or 30-somethings. It is a car for a 50- or 60-somethings that simultaneously says you’ve arrived, and also you also still know how to play. Oh, it also signals that you have the financial backing to maintain it. When it runs, it runs well. When it breaks, it breaks expensively, at times very expensively. But in all, it is my favorite car, my favorite luxury car, and my favorite sports car all-in-one. When I close my eyes and imagine the perfect car, this car is where I am when I open my eyes to drive. PROS: beautiful classic design, excellent materials, exhilarating acceleration, wonderful exhaust song, transforms from real coupé to real convertible in 16 seconds, brilliant suspension that allows a very heavy car to respond like a lighter car. CONS: expensive to operate, breathtakingly expensive to fix (example: new MB battery is $650). Heavy. Seat level is quite low so getting in & out is “challenging,” electronic controls are aging poorly (COMAND system ugh). Final take: every car design is a compromise between many factors. I think the key is finding a car that fits “your needs and wants.” Even then there will be points that rub you the wrong way. The SL is not a perfect car, but it’s compromises place it in a subtle niche between performance and luxury that few other cars can attain. This is one car you must live with awhile to decide if the price of entry and maintenance is worth the exhilaration for. you. For me, it is. Happy Driving!
