The Bottom Line

What do the About.com Rating stars mean?

The SLK55 AMG is the hot-rod version of Mercedes' two-seat retractable-hardtop SLK roadster, which received a thorough going-over -- including updated styling and an improved interior -- for 2009. The SLK55 AMG gets a 355 horsepower 5.4 liter V8 (link goes to photo), 7-speed automatic, upgraded suspension, steering and brakes, and a premium leather-lined interior. The SLK55 AMG looks good and goes fast, but is it worth buying? Read on.

Guide Review - 2009 Mercedes-Benz SLK55 AMG

For the most part, I like the SLK55 AMG. I like the way it looks, I like the way it goes down the road, and I really like the way it develops power. The SLK55 reminds me of a creature from one of those battle-card-themed cartoons my kids watch: It's cute, cuddly and friendly, at least until you floor the accelerator. That's when its eyes bug out, its hairs turn into poison-tipped spikes, and its contented purr becomes an ear-splitting yowl. It's almost a shame the SLK55 is so sedate when you're not giving it the juice.

But there's one big thing I don't like about the SLK55 AMG, and that's the price. The SLK55 AMG starts at over $66k with destination and gas guzzler tax. Options on my tester included navigation (which should be standard on a car this expensive), AIRSCARF (which blows warm air on your neck), and a fancier climate control system. Bottom line: $72,145. Someone get me a chair! For that kind of money, you could buy three Mazda Miatas. You could also get a BMW M3 retractable-hardtop convertible, which comes with 4 years of free maintenance and a higher fun factor. Me, I'd probably go for a soft-top BMW 135i convertible. It's not as fast or as small, but it's still plenty thrilling to drive, and even with all the options it's over $12,000 cheaper than a stripped-down SLK55.

There have been rumors that AMG is going to fit their 6.2 liter V8 into the SLK and create an SLK63 AMG, though as far as I know Mercedes hasn't confirmed this. Even if it wasn't any faster -- though I'm sure it would be -- the 6.2's wrong-side-of-the-tracks demeanor would give the SLK the one thing it lacks: full-time attitude (as opposed to the part-time 'tude of the SLK55 AMG). Now there's a car that would be worth spending way the hell too much money on. But the SLK63 doesn't yet exist; the SLK55 does -- and my advice would be to take a pass. -- Aaron Gold
