Great service at J Star Dodge
J Star Dodge has the best customer service of any place of business I frequent. They have been the only place I use to service my 2019 Dodge Durango. I have 69,200 miles and it runs like it’s brand new.
Great Buy!
This truck is amazing. Turning heads all over as we tour the area. Those riding with is also enjoy the comforts and safety features. Great Buy!

Happy Customer.
After getting the run around from multiple dealerships in LA/OC/IE I visited Auto Republic. Yes, I had my guard up after all the financing and heavy down payments other dealerships we're asking for before even giving me attention. The showroom was clean and the lot had so many dream cars. I found the perfect car for my family and had the assistance from the manager that was top notch. I'm writing this review since the single star reviews show the lack of reading details about add on features. Don't get upset with a dealership for having tracking on a car (saves on insurance) along with other key options that are great for your next car. I've referred family and friends, all had exceptional purchasing experiences and I'll get my next vehicle here as well.

The prices attracted me. The customer service and experience/ level of knowledge was not great. There was an inconsistency of dealership policy. It would be nice to get a car for the price you expect. I felt forced to purchase items I did not want

I called the dealership and spoke to Gary Koch.
I called the dealership and spoke to Gary Koch. I found him to be very personable and knowledgeable. We discussed the online price and agreed to purchase the car. I am not local and handled the preliminary paperwork over the phone. Once everything was confirmed I booked a flight and Gary offered to pick me up. I was in and out of the dealership in less than 90 minutes. Gary made the car buying process super easy and enjoyable. I also received an exceptional deal.
