Hi-Power (Ernesto) took your advice and has had work done on both his 300E and E420 at Enrique's shop and is a convert.
He was so happy with the work and reasonableness of the charges, that I think I'm going to take my car to him, as well, in the future.
It's about 35-40 minutes from Diamond Bar to Tarzana, but it's probably worth it.
Besides, if you look at a freeway map, it's almost a direct shot from my house if you draw a straight line - 57 north to the 210 west, which automatically turns into the 134, which automatically turns into the 101 going to Ventura. Beautiful.
