My favorite shop was Pacific Motors on Pico and 7th in santa monica (1 block north of Lincoln Blvd.). Ask for Rick and tell him that Igor sent you there. He has an excellent mechanic by the name of John. These guys are just great. If you do go there tell him that I just turned 300,000 miles on my 260E in Minnesota.
