The day after I brought my pickup home following the on-star module replacement, I noticed some body and paint damage that could only have happened at the dealership. I had no real proof of this, only my word. Rob C inspected my vehicle and told me they would make it right. A week later my pickup looks as good as new and no charge to me. Thanks Rob and Corwin GMC!

A very pleasant and encouraging engagement. The experience could not have been smoother. I’ll tell everyone about them.
Versatile and comfortable hauler
This SRW truck carries a slide-in truck camper and tows a boat when it's not a daily driver. The gas 6.0L is very capable to handle both and the truck is comfortable riding when not loaded down. Reliable engine and truck.

The experience with Leanna Tabora was great.
The experience with Leanna Tabora was great. She helped me from my initial request on the vehicle and walked me through the trade in perfectly. Given that I was in San Diego, I was not sure how the trade would work out but everyone and dealer followed through with their commitment. Oscar with Finance was great got me in out within about 20 minutes. The entire transaction took about an hour and a half from when I arrived with my trade in vehicle.
Great truck
This is a very clean, serviced and useable truck. I "live" in my truck and needed reliability, but without the garish price of new. All my tools fit and it is very handsome interior and exterior.

I really enjoyed my experience with Kale and whitewater
I really enjoyed my experience with Kale and whitewater when buying my vehicle. I drove 3 hours to make the deal and Kale had facetimed me and sent me numerous videos and pictures of the vehicle so I knew what condition the vehicle was in. When I came in the store they had everything printed and ready to go for me so after the test drive I got in and out very quickly. Highly recommend working with them!

Unexpectedly Surprised!
Unexpectedly Surprised! Jim, aka Turk, the 2nd generation owner of Diamond Jim’s is a 10 out of 10 and if the scale was out of 100, he would be a 100 out 100. Here’s my story: I have had over 35 Corvettes and had been looking for a 2015 Corvette - Daytona Sunrise Orange Metallic - convertible - 7 speed manual for 18 months and finally found one and it was at Diamond Jim’s in Milwaukee, WI. I called and spoke with Jim and he suggested that we FaceTime and we did for it a good 20 minutes. Car was great except the tires were a little worn … not a problem … I put a deposit down and scheduled a flight from Southwest Florida to Milwaukee with the plans of driving it back 1,430 miles! 🤪 I have never flown cross country to buy a car before so I was a little nervous to say the least. We arrived at Diamond Jim’s and met Jim … the car was everything he said it was and better (fair price too)! This is when things turned to the unbelievable and quiet frankly, shocking … Jim said he felt uneasy selling me the Corvette with the slightly worn tires so he replaced them with brand new OEM exact factory replacement Michelin tires!! I have another, identical Corvette and recently replaced the tires on that one for a whopping $2,000!! 🫣 Jim apologized for not giving me a full tank of gas (it was 1/2 full) … I said, “Let me see, a full tank of gas or $2,000 worth new tires!!” He laughed and said the construction in front of his dealership prevented him from filling up the tank! He’s a true gentleman. Then, to add to this amazing person that I just met, Jim called us about 2 hours later during our drive home making sure that we were doing OK!! Lastly, we plan on buying another car within the next year and there is no doubt that we will call Jim, take his word for the description of the car, pay for it and ship it to Florida … we drove the 1,430 miles in 28 hours and we don’t plan on doing it again! 😁 I have been buying cars since the late 1970’s and I have never had a better experience than I did with Jim at Diamond Jim’s and I give them the highest recommendation possible!! 👍

1970 Ford Torino
Out of state buyer, I purchased my 1970 Ford Torino. My sales person was Terry throughout the whole process. Not sure other buyers in past didn’t do their research before buying but overall this company and sales person Terry took care of me and worked with me. I hired a Mechanic to look at the vehicle we came to an agreement that satisfied both of us. Had my car delivered and was very pleased with my purchase. Thank you so much. I’ve been waiting so long to get my old car and relive my past!
