Why don't you just put it on yourself? It should be relatively easy.

I've never done one and the guy I am buying it from actually offered to install it for me included in the sale . Then I read how to do it right & I figured it is best to make sure nothing is done wrong and everything is done right and since its the way you stop the car that taking it to a mechanic in this case would be best. If he has the time on Friday I would also consider going down 1 hour to Miami and working together to see its done properly..

So are you paying the bill for this or is the seller? If seller, I pick Toyota guy since he's closer. If it's you, I still recommend DIY. A brake booster swap is one of the less difficult repairs you can do to a car, Mercedes or not. The only part people seem to have trouble with is getting the brakes bled after they put the master cylinder back on, and there are extensive threads on this forum describing how to accomplish that.

Take it to the closer guy if you know him. He can easily figure out a MB brake booster. It's not rocket science.

Given the emphasized language in your reply above, I would take it to the Benz guy, since you express the concern as you do.

Although I also agree with the others that replacing the booster is not the worst job you can do on a car. After all, if you get that done and run into trouble bleeding the brakes, then you can have it towed to the Toyota guy.

Good luck.
