87 BMW here. I believe my servo is controlling the throttle cable itself. When the cruise control commands the vehicle to accelerate, the pedal physically moves.

It's not my daily driver, but I would absolutely love to one day get another one as a project car - one that's not in such good condition that I'd feel bad removing the engine - and drop an electric motor in it. That likely _would_ become my daily driver. The car's incredibly well made, and a joy to drive.
