The dealer in San Bernardino is Doug Douglas Triumph. Tiny little shop on fifth street. Very nice people who take good care of their customers (no, I have no affiliation with them). The owner is Art who loves Triumphs and knows his stuff. They now also sell the new Royal Enfields. This dealer and the dealer in Brea are the only "platinum" dealers for Triumph in Southern California. The shop in Lomita is either silver or gold. OTD is not on the list and I have heard they have filed for bankruptcy. I like both Brea and Doug Douglas. Tom is the owner of the Brea store and he seems very nice as well. His shop will have the larger selection in stock. Both Brea and Doug Douglas have bike events each month with the one in Brea being larger. When I get my new T bird (hopefully soon) I will check both places. My guess is that I will get a better deal at Doug Douglas, unless I want something hard to get like the new red thunderbird se. Hard to find bikes are probably going to be in Brea, ready for immediate delivery.
Good luck with your decision. Let us know how it works out and where you end up buying it. Both Tom and Art are nice and patient with me for all the times I go in and sit on the Tbird and make vroom vroom noises
. Either one will take very good care of you.
