Car Source review

Car Source David Gurevitz Oct 13, 2025 “ This is the 2nd car I bought from Alonzo at Car Source. I found him to be one of the best. As the same as the last time, I told him what I was looking for and a few days later he found it. In the past, I have tried this with numerous other car lots. And needless to say, have never been successful. Alonzo always comes through. He's very professional, but also honest and down to earth. Thank you for being my "go to guy". I appreciate you...

Hugh White Honda review
First, I do have to say that Jordan is a pleasant,
First, I do have to say that Jordan is a pleasant, respectful, "upcoming" used car salesperson. With his outgoing, friendly, respectful demeanor, he likely could have sold me just about anything. On President's Day, my husband and I drove about 45 minutes, intending to test drive a specific Wrangler at the Used Car division. The test drive went well with us both falling in love with the vehicle. The negotiations went fairly quickly, despite me having no access to my bank to move around $$$$$ and my trade vehicle not being present. There was give and take on both sides- mostly give on mine, LOL. We arrived at an amicable deal on the price, trade, service contract and promise to fix the heated steering wheel. Ziggy, the finance manager, was pleasant and efficient. We waited an inordinate amount of time for the title work on my trade to be done. On Wednesday as planned, we returned, with my trade and a check in hand. Apparently Jordan forgot that we were coming as we waited over an hour for the vehicle to be "cleaned and readied for delivery." The dealership was not busy at all that day, with staff congregated around the main desk, laughing and joking. Any other time that I have purchased a vehicle, it has been serviced, cleaned, washed and waiting near the dealership entrance. When Jordan finally handed me the key, confirmed that there was no spare key and informed us that the steering wheel parts were on back order (and could take up to 30 days to arrive,) he bid us good bye and good luck. I asked, "so that's all? Is there anything to sign?" Both Jordan and the Finance Manager assured us we were good to go. Everyone had a good laugh when I asked them if they wanted the $27,400 check. Maybe the laugh will be on me if the documentation I have does not show that they received the check. I have to say that the experience was mostly positive. I only wish that the staff had been more prepared for us to take delivery. Jordan did get some points back when he filled the fuel tank before we left. Time will tell about the steering wheel issue.

My GMC Sierra is the best ride I have had in all the years that I have been driving. I started driving in 1977. I love my new Sierra.

My experience at Ricart Used Cars on Billingsley was one
My experience at Ricart Used Cars on Billingsley was one of the best car buying experiences I’ve ever had. From the moment I arrived, I felt welcomed by the sales team. The entire process was smooth and hassle free, with no pressure in my decision. A big thank you to James and Andre they were incredibly welcoming and great to work with. Ricart Used Cars has earned a customer for life!
