Get KYB monotube shocks and struts. Most MB owners are deathly afraid of anything made in Japan so these end up being an extremely good value. Also these will far outlive the garbage Bilstein is manufacturing today in Eastern Europe and China. Try finding a monotube Bilstein or Sachs shock anywhere near this price.
really? every time I put KYB on a car, they lasted 10-20K miles then were mush. Most recently, on a 2004 Camry LE, when KYB was about the *only* shock I could find. previously, I used them on a 1989 VW Jetta GLI... after 2 sets of KYBs I finally listened to someone smart, and put Boge Progas on that car (along with Neuspeed progressive springs) and those shocks lasted the last 120K miles I owned it and were STILL damping as good as new.
My wife's 94 E320T, we put bilstein touring on the front when we got it (the rear of the wagon is SLS of course), and its still riding and handling great and she's put like 40K or 50K miles on that car and often drives like a teenager.
When I got my 93 300CE Cabrio, it had nearly new Napa shocks which I determined were rebranded Monroes, when I first got it, it was tracking the road just great... 10k or 20k miles later, they are mush, and the car is wallowing on the turns and on bumps. I'm about ready to think about a replacement. sad, but I'm not sure the proper strut mount for the left front shock which is under the vibration damper plate is available anymore, and IIRC, the cabrio uses very specific shocks. I kinda wish I could convert my cabrio to sportline, but I just don't think that's an option I can afford, so I'll probably get Bilstein HD and see how they work.
sad, I know, ALL these brands are selling junk now
