As wonderful as the Benz Cruise control works, it will most likely fail.

They seem to be good for about 125 M miles and then they get winky. And no one seems able to fix them. Even if you spend lots of money, and you will.

My 86 diesel at 280M miles works unless you hit a bump.
My 91 SEL at 147 miles worked if the AC compressor fuse was blown
My 90 SEL at 120M miles works when ever it choses too, which can be a bit of a surprise coming off the interstate.

The XFire is my fourth Benz product and the only one that still has a reliably working cruise control. I will never trust it. I won't try to fix it when it goes, in 2016 when the warranty is out.

But I do like it's ease of use. Best ergonomics ever.
