Call Harry Appleby at Viking Motorsports in Costa Mesa (714) 979-1020. He's very well-connected in the Lotus universe, and he knows quite a few Elise owners in the So Cal area. He can probably hook you up with someone down here who you could visit (it'll be worth it, believe me!), or recommend someone up there that you can call.
Alternatively, I would call a Lotus mechanic in the Bay Area. They should be able to refer you as well.
