SMART, a private party, but, I know it is a G & K conversion. I would be very interested in sharing information w/ other local L.A. owners re parts, tires, and service. Right now arranged just light maintenance support from absolutely GREAT mechanic I've known many years [Jim Matson Automotive on Pico], but want to be prepared just in case anything major, beyond what he can help me with, comes up in the future.
