I'm in Irvine and I've been going to Lotus of San Diego. Here's the scoop on why:
1) You only have 3 choices, EuroCar, Galpin (no service at Beverly Hills only in Van Nuys) or Lotus of SD.
2) EuroCar is the obvious choice, but I went to go check them out in person and let's just say I didn't get the warm and fuzzies. I'll leave it at that.
3) Galpin has a great reputation from a service perspective and a huge company. So this should be the next obvious choice. However, being 75 miles away and in Northern LA, at any point of the day, this is roughly a 1.5 - 2 hour drive for me from Irvine.
4) Lotus of SD is 85 miles away but at any point only 65 - 75 minutes away. So, it won for me from an accessibility perspective.
5) But the real reason I chose them, the service. Peter C., their service writer is great and their technician would send me videos and show how clean their work was (wiped down all serviced areas, would clean up areas of oil and dust residue, etc. on anything he touched).
I hope that helped, but again everyone has different priorities. So, I'd encourage you to check all 3 out.
