Loved our experience at Lum's!
We had such a great experience buying from Lum's. They allowed us space but we're still available, the provided us a great deal, they were friendly and the process was quick and without a bunch of wasted time. Our salesman was great, the sales manager was great, and the person we signed with was also great. They all spoke highly of each other, which speaks to how they are treated and valued by their leadership and it's important to me that I do business with places that are good to their staff. I highly recommend Lum's.
This truck has a jerk when changing gears sometimes.

*Exceptional Car Buying Experience at Beaverton Car
*Exceptional Car Buying Experience at Beaverton Car Company* I recently had the pleasure of purchasing a car from Beaverton Car Company, and I am delighted to share my exceptional experience. From the moment I reached out to them, their team demonstrated unparalleled professionalism and dedication to customer satisfaction. I had a very specific car in mind: a 2022 White VW Atlas SEL R-Line with black interior. Finding this particular model and color was quite challenging, but the staff at Beaverton Car Company went above and beyond to meet my needs. They diligently searched their inventory and network, providing regular updates and reassurance throughout the process. What impressed me most was their commitment to transparency and honesty. There were no hidden fees or last-minute surprises. The entire transaction was smooth and straightforward, making the car-buying process stress-free. The customer service at Beaverton Car Company is truly top-notch. They took the time to answer all my questions, address my concerns, and ensure that I was completely satisfied with my purchase. Their attention to detail and genuine care for their customers set them apart from other dealerships. I am now the proud owner of a 2022 White VW Atlas SEL R-Line, and I couldn't be happier with my purchase. I highly recommend Beaverton Car Company to anyone in the market for a vehicle. Their dedication, integrity, and exceptional service make them the best choice for a seamless and enjoyable car-buying experience. Thank you, Beaverton Car Company!
