My second SLK!

Leased one then another so have over 5 years experience. Plenty of acceleration and fun in the curves. Before we leased the first one I told my wife we'd need to be able to fit two carry-on luggage bags in the trunk with the top down. Passed the test easily with some room to spare!! Not sure but doubt u can do that with a Z4 or Boxter. It's amazing how much space there is with the top up- even got two sets of golf clubs in there. (OK drivers were in the front. All in all a very practical and functional car for a sports car! This lease is up in December and will probably get an SLC next!

Firstly this is the second SLK I have owned. The first being a brand new 2014/ (2015) SLK250 model. The first 6 months it ran like a dream, and then during winter, I noticed an odor occasionally coming into the car. The closest description that I could offer, that other passengers identified too, was like a burning crayon smell. I tried to work out when it was occurring, and the possible cause. After a few months of deliberation, a myself and a few passengers of my vehicle came to the conclusion that the anti-corrosion materials (coating) used in the body of the car, had was melting a low heating point, and at some point hitting hot parts in the engine compartment. This would start out as a slight odor, but over the coming months intensify as the days got hotter, to a bad odor, and fumes that were now getting into the cab of the car, with the top up, or down. I reported this to the dealership, and it was a game of tennis over about 4 more months going back and forth with them trying to replicate the problem when they were in possession of the car. They reported it to the regional technical rep (in NJ not far from MB USA headquarters), and after the first attempt of adding more of the soundproofing materials to the engine compartment bulkhead, and stripping the doors and cleaning them out from a very large amount of the anti corrosion / wax substance, seemed to make the issue worse. The dealership did was as helpful as they could be, but handed me off to corporate to try to come to a resolution. The only resolution that could have corrected the car, was to strip it down to the frame/body, and dip it in a bath that would remove all the anticorrosion materials and start again. Not practical on any car, so I was offered a buy back deal. After many months of passenger headaches, myself wheezing and breathing issues from the car, a settlement was reached to buy back the car and purchase a 2016 model (SLK 300), which I currently own. Now my theory was, that a different model, at a completely different time off of the production line should be far enough away from the original car in time etc, that is should not have the same problem. The old SLK 250 you could see the wax like substance coming out of the door through the rubber grommets and dripping down, also from the engine compartment when you opened the door etc. Now I have had the new SLK 300 for a period of 5 months when I started to notice the same problem. Starting with a slight wax/crayon smell, and as the next few month rolled on, and the heat of summer hit on top of the cars engine heat, the exact same issue with fumes coming into the car, when driving, generally any speeds above 40 mph with the top up or down. With all this, I can only assume it's the entire production line that has this issue, and the routings in the car's assembly instructions and details have had too much of this compound specified so as to prevent rust, but not melt at low temperatures and overspill to the engine compartment and hot parts around the bodywork. A complete shame, and downside of an otherwise fun, and fantastic car to drive. True roadster, and enjoyable drive. With this, happening, and from what I can find using google across the last 5 - 8 years of owners, I am not the only one with this problem. I can NOT in any way recommend this car to anyone, or say I will every buy this model of car again, and as it was such a fight to get Mercedes to recognize the problem the first time around, would probably never buy a Mercedes again, even if this issue was limited to this Model of car. If you find this review helpful, then my job is done. If you decide to take the gamble, I can only offer you good luck, and hoping your car/model does not have this issue, you have as much fun as I have had driving this car, prior to these issues arising. GOOD LUCK, and FUN SAFE DRIVING.

This is my 3rd SLK and the only problems I have experienced are a dead battery (replaced by Mercedes Roadside Assistance in my driveway) and a fading of the 2 rear window panels (replaced under warranty by dealership). The electronic convertible top function is smooth, quick, easy to operate, and surprisingly there is room for 2 - 3 weekend soft bags in the trunk with the top down. The interior is small but not cramped. Even on long trips it remains very comfortable (Yosemite, Park City). I have owned a Porsche, BMW and Alfa Romeo GT and my SLK is by far the best sports car I have ever owned! I live by the beach and there is no greater experience than cruising the Coast Hwy with the top down on a warm summer night.

I have had the 350 for a year now. It feels quick in sport mode and is easy to drive around town. It is not a Corvette, but has enough power to be fun. It is a convertible, so don't expect a rattle-free ride, but it is surprisingly quiet and smooth compared to other convertibles. I drive it 65-70 on the freeways with the top down and can still hear the radio just fine. The Miata is definitely fun as well, but it you can afford SLK (even the 250) I think it is worth the extra money. Passenger side leg room is tight and uncomfortable for anyone over 5'9". Driver side is probably OK for up to 6'0".
