Jim (Sales) and Christian (Finance) were fantastic to
Jim (Sales) and Christian (Finance) were fantastic to work with at West Side Lexus. I worked with Jim during the week to secure a Saturday appointment. Arrived at 1109a and was driving off the lot in my “new to me” car at 12:35p. Everyone there was friendly and the customer waiting area is great, lots of space and a pretty decent hot chocolate in their fancy coffee machine :D 10/10 recommend
Love this car

Better sales experience this time - no issues
In the interest of fairness, I wanted to follow up on the negative review I left on Dec 20, 2022. The dealership, specifically Shaun A reached out to me and apologized for the miscommunication and inconvenience they put us through. And after some discussion, he agreed to lower the price of the the Edge that we were interested in by $500. It was an overall good deal and my wife and I accepted the offer and completed the sale that same day. No issues with the sales process and the paperwork was handled professionally and efficiently.
Best SUV we've ever owned.
Exceptional vehicle in the SUV class. We drove the BMW X7, Audi Q7, Volvo XC90 and this GLS 450 just kept blowing them out of the water. The ride is amazing and we feel the comfort level and size is the best

This time my tire pressure light was on so stopped in to have them checked. Always friendly and efficient intake. Service is a job done well in a timely manner.
You get what you pay for
We are in our first five months and I seriously believe all the safety options have kept me out of at least two accidents. The car on the highway practically drives itself while giving me a message. Audio systems are excellent. The 450 GLS makes driving a bit of a joy.

Customer service has certainly changed since purchasing
Customer service has certainly changed since purchasing my first auto in 1971- a Ford Fairlane 500, with bucket seats and the shift between the seat. It was constantly in need of repair. Thanks to the great service department at Sam Galloway, my car is never in a state of repair. I took my Corsair in for a scheduled Protective Spray coating. And thanks to my service Rep, Jamie, who advised me that my service was coming due, they were able to take care of that too.
Great car!
Luxurious to drive and very quiet riding car. I am very satisfied with the car. The electronices are a bit over whelming at first. Love the car.

Simply the BEST ever!
The team here is second to none! The service is stellar across the board. I have NEVER had such a pleasant experience when buying a vehicle. IThey truly do treat you more like a family friend than a bag of money. The personal aspect is what makes me smile when I think of this team. Shout out to Brian and Clay in Sales and Jerry in Finance. These guys are amazing! I wish I could just hang out with them since I don't buy cars THAT often. lol You won't find a better team in car sales!
Great Electronics and Engineering
This car is state of the art in human factors engineering. It has multiple layers of safety enhancements. Interior is very spacious. The 42 volt battery provides quick acceleration which allows the car to have no lag time when accelerating.

Had an excellent experience with the dealership. They had the car washed and ready for my test drive. The sales person brought us through a thorough road test and answered any questions we had about the car. The sales experience was seamless and I highly recommend this dealer.

Great place to find a used car!
Fantastic experience at Sterling Heights Dodge Chrysler Jeep Ram! Joe was great to work with and made the buying experience very very easy. Joe Ancona from used cars was great! Started with email and then in person. Very knowledgeable and personable. He took care of me from start to finish. I recommend everyone go see Joe!

I had the best experience with purchasing at this
I had the best experience with purchasing at this dealership. They are well known for having luxury on a budget vehicles. Financing available, fast & easy, accepted my trade in vehicle and gave me more money than any other dealer offered on the value. My credit is average and I still got a low payment, very nice! Friendly service from Kirk, Andy, & Nida, they make you feel right at home and walk you through the entire process, only taking about a hour of my time. Very efficient this place. Drove off the lot with equity, not a losing value scenario like at a new car dealer. Thank Texas Car Club!!!

Mercedes Benz of Escondido
I was amazed by this dealership. From service to sales, everyone was so kind and helpful. I bought my 1st Mercedes here (2022 C300) and Patrick was there to assist me and make the experience the best one yet. Highly recommend this location for either getting your car serviced or buying a new Car!

I had a great experience working with Bill Holcomb at
I had a great experience working with Bill Holcomb at AutoLenders in Newtown Square, PA. He was knowledgeable, professional, and made the entire process quick and stress-free. Bill really took the time to understand what I wanted and went above and beyond to accommodate my requests. He also worked hard to get me the lowest monthly payment possible, which I truly appreciated. If you’re going to AutoLenders, I highly recommend asking for Bill Holcomb—you won’t be disappointed!
