Good Dealership
Thanks to Alfonso I purchased my long awaited Ford Maverick. Alfonso was very helpful and patient with questions I had and offered after purchase assistance with anything else I needed. Also to the finance guy (sorry forgot his name). He was really helpful as well.

Super impressed with this dealership. Not at all what you'd expect in a "city" dealership. Spotlessly clean, open, bright . . . and friendly. Plenty to choose from. Didn't feel pressured at all. And they were very flexible (I can be kinda demanding). Great on the price. Highly recommend this store! i know some people scared about salvage but you fill comfortable when they let you to take it to your own mechanic shop or local dealer to check, they also give us warranty as no cost.

Shop smarter Not Harder
To me these reviews all sound like everyone wants what they want this is a business that’s selling used cars a tip to help new buyers. You are given a 500 mile or 15 day warranty take the car you buy down to the original dealership or any mechanic have them do a over all inspection if anything is wrong with the car that the warranty covers take it back to the place you bought it from and they are legally obligated to fix it at their expense not yours because it falls under the warranty also make sure you buy GAP INSURANCE AND ANY OTHER EXTENDED WARRANTIES REMEMBER THIS IS YOUR MONEY AND INVESTMENT!!!!! Hope that helps anyone out on here or anyone looking for a car. I AM NOT A LAWYER & THIS INFORMATION IS BASED ON A PERSONAL EXPERIENCE…..

First I have to say that I am NOT a review leaving
First I have to say that I am NOT a review leaving person, with exception Of Lifted Trucks. In the last 6-7 years the only reviews I have written have been for this store....on with the story... I just purchased my 4th Truck from the Glendale store . This is the 4 truck in 6 six years. The staff does NOT get any better then these folks. From the warm and inviting welcomes to the store to the Superior Management. These are the best people around and I can't thank the enough. I am a customer for life. Thank all of you Sincerely Dan Hubbell

Actually not a bad place to buy a car.
Actually not a bad place to buy a car. I mean, it’s still a car dealership and the usual shenanigans apply, but they will negotiate, and they’re civil and professional. And they give you top for your trade, as I’ve shopped 4 other dealers, they were the best by thousands. Management does a good job too. Frank in particular is a good TO guy. All in all, if they have the car you want, buy from them. You probably won’t do better anywhere else
