I recently purchased a BMW X7 from Auto Giants
I recently purchased a BMW X7 from Auto Giants Mitsubishi, and I couldn’t be happier with the entire process. The staff was professional, knowledgeable, and really made me feel comfortable throughout the sale. They were transparent about everything — no hidden fees or pressure. The car was in excellent condition, exactly as advertised. Special thanks to the sales team especially to Jacob and Philip for their patience and excellent customer service. If you’re looking for a smooth and trustworthy car-buying experience, I highly recommend this dealership!

On Friday 8 December 2023 I took my car to Oursman Jeep
On Friday 8 December 2023 I took my car to Oursman Jeep in Bowie , Maryland. For whatever reason the computer would not recognize the key when trying to initiate ignition. At Ourisman Jeep the service advisor , Mr. David Valenzuela, listened to my concerns and, at no point, did he interrupt allowing me to to clearly present the problem. He asked me a handful of questions to narrow down the possible cause of the problem . A short time later he decided it was not the car itself but the fob battery. He replaced the battery in both of my fobs : problem solved! I certainly was impressed with how he deduced what the cause of the was. As impressive as the problem solving was , what was equally impressive was his command of "Customer Service 101". Eye contact, respect for me as a customer/ human being and not as "the guy with the malfunctioning Jeep". He was patient to a fault. Great example of "just getting the job done the right way". 5 stars, at least.

The car was as described and the Sales person ( Kevin Soltwedel) was available on his day off to show me the car after communicating via email. I eneded up purchasing the car and there was little hassle in doing so. I had one small issue with the key fob missing the key blade ( $30) part and initially dealership wouldn't agree to replace it. After some back and forth with my salesman, they finally agreed to make it right. I did feel that my salesman had to work too hard to rectify the issue internally at Land rover Bethesda, for something that should have been a non brainer
