I've had my SLK55 for about 14 months now, and I can't get enough of it. It really is the perfect car. Some cars are great for specific things, but the SLK55 is just so well rounded.

On one hand, it's a perfectly comfortable cruiser with a smooth transmission and engine, comfortable seats and a good stereo.

On the other hand, that same engine is brutally powerful and well matched to the chassis. The handling really is quite good, and it can hang with the more dedicated sports cars like Porsches and BMW M cars.

It's also a coupe and a roadster with the push of a button.

I love the R171 so much that I had an SLK280 for 3 years and now have a SLK55 that I don't plan on getting rid of any time soon.

I put together a quick video with a dyno run and a few autocross runs. The run in the rain was from this past Sunday. I did my runs when the rain was at it's worst, and had the fastest time of my heat by 0.8 seconds. As the day went on, conditions improved but my time still held on for 8th place overall out of a field of 81. Not bad for a mostly unmodified Mercedes AMG.

People made fun of the car at first. "Why'd you buy a girls car?" "Should have bought an M3 or something" Not anymore!

Nice video! I really like the colour combo on the car BTW.
It would be nice to get some video of the car running the course too!

Sweet video. I also had a 2005 SLK350 for 6 years before trading it in for a SLK55 R171. I don't think I ever got a "girls car" comment. :biglaugh:
Did you get any before dynos without the filters, x-pipe, and secondary cat delete? I only have the aFe dry filters on right now. I think your next mod should be an ECU tune.

This is the only video I have from outside the car. Recorded by my girlfriend the first time I took the '55 out to autocross.

I dyno'd before the air filters. When I swapped them, the old air box was filthy! I probably gained some power just by adding clean filters!

If anyone has any input on the eurocharged SLK55 tune let me know! I already bought it, but haven't had it installed.
