As a customer at West Covina Performance Ford, Manny Hernandez is the most knowledgeable and helpful salesman I've ever dealt with and as a new contact Fiona Doran is service is spectacular. I had an unexpected leak in my rear axle of my truck this week and she got my truck in and out in a single day!!!!!!!!! At a dealer!!!!! She kept her word on the time frame and kept me informed. This was so important because I am leaving this week to go on vacation and needed my truck in tip top condition. She saved my trip!!!!!! I highly recommend this dealer and Service department!!!! Manny and Fiona ROCK!!!!!!!

I bought a used car that was highly sought after, based
I bought a used car that was highly sought after, based on it having only 2k miles per year and it's price point. I worked with Ed, who went out of his way not only to reassure me that I had secured my spot as the buyer, but also provide me with photos and updates as the car went through the reconditioning and detailing process. Ed was extraordinarily responsive, answering my (many) texts within minutes! Ed demonstrated exceptional professionalism, caring and compassion. I would buy another car from him in a heartbeat.

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.
