Very honest and reliable mechanic shop (with a bad acronym) specializing in all makes of Japanese cars... and, for reasons best known to the owner, Saturns. These people are absolutely ethical, charge reasonable prices, and do small jobs for free.
As a result, they are generally booked completely solid for months ahead. But try them anyway!
