Frustrated Mirai owner
Great dealership but do not believe the hype on the Mirai! Often impossible to get fuel in the San Gabriel Area. Stations are off line more often than not. It is like living during the oil embargo of the 70's with no end in sight. Spend hours looking for a station, you find one online and wait for another hour, only to experience a mechanical issue. Great car just can't drive it.

Got my new car!
On April 6, 2023, I took delivery of a 2023 Yukon Denali Ultimate, which was a SUV that I ordered, equipped the way I wanted it. John and the entire sales staff were great! I have purchased/leased 4 other vehicles from this dealership and have always been treated well. If you want to avoid all of the seemingly normal drama that goes along with walking into a dealership, you need to try this one - you'll be pleasantly surprised.
Nicest, best performing truck I've ever owned
My truck has a great appearance, inside and out. It is a pleasure to drive; and rides and performs great. It is the best truck I've ever owned.
