Best experience ever at a dealership
dealerships on how to treat customers!!!! This was the BEST dealership experience we've ever had in our lives!!! Chris Dargan was amazing!!! He was courteous, professional, knowledgeable, and treated us with the utmost respect. Chris never tried to overcharge us. Bert Dutcher was awesome as well!! Bert was upfront about everything and never once did he try to convince us to use their financing. Bert was professional, kind, personal and patient. The only bad thing about Bert was that he wasn't a "Dallas Cowboys" fan!!!! When you're ready to purchase your vehicle and you want to be treated with dignity, come to Rizza!!!

Great service
I was in and out in less than an Hour. Everyone was very pleasant, the paperwork was explained in detail. They allowed me to leave my other vehicle there until someone took me to pick it up. From the time I entered ti the time I left I felt very comfortable.

I've been coming to JLR South Shore for years and have always received impeccable service. They have taken great care of my 2019 Discovery Sport. Jordan is a great employee and they are lucky to have him as well. Have also spoken with the dealer (Kirk) a few times and he's a funny and humble guy, didn't even realize he ran the place

I initially checked to see if the SUV I found on cars.
I initially checked to see if the SUV I found on cars.com was still available to look at. After sending the email, via cars.com, I got a text back within a few minutes saying the SUV was available and a salesperson would check with me to set up an appointment. I spoke with Jamie shortly thereafter and met with her at the dealership. The SUV was washed and ready for me to see and test drive. The rest of the purchase experience was fantastic!! For me, number one of the top three car buying experiences ever. I’m now retired and have bought a lot of cars. No high pressure, just great customer service. Keep up the great work Jamie and Bettenhausen!
