As good as it gets

2008 Mercedes-Benz SL-Class SL550 2dr Convertible (5.5L 8cyl 7A)

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.

The SL63 AMG has the multi-clutch transmission. It does not shift as smoothly as an automatic with a torque converter, but once it's warmed up, shifts are quick. Make sure to get the extended warrantly. The roof, shocks are hydraulic and they can get expensive to repair. Oh, be light on the right foot or you'll be refueling around every 120 miles.

Not worth the money...

I was a big fan of Mercedes prior to owning my 2009 SL-63. After having it in the shop for now the 4th time in 5 months, they still can't fix the transmission and excessive oil burn. The new transmission slips like you've lost gears until the car is completely warmed up. Try pulling out into traffic, stepping on the gas and the engine revs, but the car goes nowhere. Then out of no-where, 3-5 sec later the car catapults you into traffic. I was finally told that this is a race- car. You can't expect it to drive like a luxury car. How about that? In addition to having to add a quart of oil every 100 miles Mercedes has some work to do before I would ever recommend this car. Spend elsewhere!

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!

What A Machine

2008 Mercedes-Benz SL-Class SL55 AMG 2dr Convertible (5.4L 8cyl S/C 5A)

This MB SL55 AMG is one of the most powerful, exciting vehicles I've ever owned. The performance is unbelievably good. I've timed my own full-bore start and got to 60 in 4.5 seconds. Handling is easily better than both a BMW M6 and a Porsche 911 Turbo S.(I've road tested both) Obviously, the retractable hardtop is the biggest party piece of the SL and it works beautifully in about 22 seconds. The interior is very well done and the Mercedes trademark massaging seats works wonderfully. But after a long distance trip, you will feel it for the ride is very firm. Fuel economy is not as bad as expected for a 500 horsepower V8. Expect like 15 city and 19 highway. Bravo Mercedes-AMG.
