My husband & I went to RIverside on 11/7/2020 with a check in hand & intent to buy a $50k used 2019 Tahoe after working with TJ days prior. After inspecting the interior & exterior & test driving, we were ready to purchase, but before doing so, we pointed out two issues: chipped paint & scraches in several spots on the truck & need for an oil change due to no oil change being done Since April 2020. It's at that time that things when horribly wrong, in which our amazing, patient, helpful, & resourceful salesman TJ relayed our concerns to sales manager JR. JR immediately came over to us and thanked us for coming and told us that he didn't want to sell us the vehicle & indicated his rationale was because he didn't want us to be uncomfortable. He informed us that there was no need to change the oil and continued to thank us for coming and reiterated that he ddin't want to sell us the vehicle because he doesn't want us to be unhappy and have regrets. Let me indicate again, JR first words out of his mouth when he approached us was indicating the need to not sell us the vehicle & thanking us for coming, I know I was shocked & appalled too. What is more consists of the fact that, at no point in time did JR validate our simple concerns or offer options to try and resolve the issues & proceeded to talk about why he doesn't think we should buy the car, as he put it, "you guys seems to have a lot of problems with the car and I just don't think it's a good idea". This comment was blatantly insensitive & inappropriate & implied that expressing our concerns about a car with several chipped paints (with risks of rusting) & the issue of no oil change in seven months seemed to be unnneccessary & unimportant to JR despite the fact that there's a general rule of thumb, that it’s good to change a vehicle's oil every 3,000 miles/3 months, whichever comes first to avoid engine failure as a result of sludge build-up, but due to JR not seeing the relevance and need, he was not open to doing so. After hearing this, I agreed that there was no need to purchase the vehicle and we in fact would not & walked away. JR then came outside as if he was now interested & willing to take a look at the oil himself after seeing that we were no longer going to purchase the vehicle. He still determined that the oil looked fine, yet offered to get it changed. However, this came way after he insulted us & dismissed our concerns and politely declined to sell us the vehicle. Furthermore, we had what started out as a pleasant experience, all thanks to TJ & ended with a painful experience. Overall, I'm thankful that I didn't make the purchase because my time and money wasn't appreciated & JR blew a $50k deal simply because he didn't agree with the need to change the oil. Also, prior to going into the dealership to finalize everything, TJ & I were walking to the vehicle & JR passed by & asked TJ if it was a done deal because he had a customer that was interested. I told TJ his comment was fake & reminded me of a bad pick up line & whether or not there was someone interested or not, it was a rude & disrespectful comment to make & if it was his attempt to put pressure on us to buy the vehicle it didn't work & wouldn't have worked. One would have thought that after having this vehicle for seven months, one would have been willing to try & do all that was needed & reasonable to help meet the customers needs to ensure the sell, but JR did see it that way. Lastly, my suggestion to anyone is purchasing a vehicle from Riverside Buick GMC is, go where you're wanted and appreciated & treated with respect, kindness, & fairness & go where your concerns matters & needs are met. Prior to leaving, we thanked our salesman TJ for all of his help & told him verbatim what the sales manager JR said & how he cost him the sell & advised that someone work with him on his communication & interaction with customers. In hindsight, I should have known better because I had spoken with JR the previous day about a buyer's order & he told me that it was an inconvenience to be "doing all of that" & questioned me about not financing with the dealership.
