I just installed an aftermarket Rostra "Globalcruise" unit in my 84 300D. Works quite well. The control stalk is obviously non-MB looking but fairly unobtrusive. The unit is a "one box" install, simple wiring and a driveshaft magnet setup for speed sensing. All electronic, no vacuum servo controlled. Its a little slow to respond when you set it and on very gentle downgrades it can "hunt" or surge gently but this only happens in very specific situations. There is a gain control I have yet to mess with but it may alleviate this issue. Once the speed is set it locks it in, no variation at all. Cheaper than a rebuilt cruise amp from GDL that may or may not have solved my inop CC. Should be able to install in any car. RT
