I think I will chime in since I am local and tell you about the SD dealerships.
I've bought my mom's '08 RX400h from Bob Baker Lexus and they were great. They treated us with respect and never looked down upon us. Even if we rolled in a 2008 Scion xB. They were great with service after the sale as well. The first service went well too and even the warranty issue with a relay we had with the RX was done right. I would definitely recommend them even if they are the smallest Lexus dealership here.
We also shopped at Lexus Carlsbad. They are great as well. They just didn't negotiate as well so that's why we ended up buying the RX from Bob Baker. But I still like them though. I take my F there for service. No problems with them. They're very personable and gave me a loaner every time. And free car washes when it comes in for service. They never looked down on me despite my age. I'm 25 though I look 2-3 years younger. I was at the dealer over the weekend and they had 3 Fs on the lot. Blue, silver, and black. Didn't take a close look at them so I don't know what year they are.
I've never been to KM Lexus. All I've heard is word of mouth and it wasn't great reviews. I've talked to internet sales, but was not impressed.
If you've got any questions, let me know. I'll help you out as best as I can. I love car shopping. One of the few that do haha. All my friends/relatives come to me for this stuff.
P.S. I forgot to mention that I bought my car from a sponsor on this forum because I was looking for an exclusive combo and option spec and he happened to find it.
