I've had nothing but good experiences with them. I've been a customer for almost a year - bought a 2010 Thunderbird (the Triumph kind, not the Ford). I had emailed them looking for a quote, and the salesman, Daniel, asked me to stop by - like they all do. When I did, I asked Daniel what kind of deal he could do for me, and he went in the back room for what seemed like a half an hour, and I'm thinking "Here we go... normal auto dealer tactics." So he comes back out and says, "If you're serious we'll knock off a thousand bucks." I was impressed and I bought the bike. I've also bought a ton of accessories there.
And hopefully a brand new black G5 deluxe! Yes, I have money down on one. However it is contingent on the bike being okayed by CARB. Last I heard (and this is third-party so it might not be true) is that CARB wanted RE to ship them a California equipped bike to they could eye-ball it. I'd say we're looking at waiting ANOTHER month before they can actually sell bikes.
If you do go to Doug Douglas, don't be put-off by the way the place looks on the outside. It's an old garage stuck in the middle of an old residential neighborhood - I'll just say it has some character.
