I did the entire transaction online, which can always be a bit stressful as the dealership is 10 hours away from me. Mike was my sales rep and I cannot imagine anyone being more responsive, thorough, and upfront about every part of the transaction. Professional, polite and personable, I always felt like I was in good hands. He picked me up at the airport, drove me back to the dealership, and I was on my way within an hour. I have purchased Mercedes, Audi, and other luxury brands, but this was by far the best customer service experience I have ever had purchasing a car. By the way, the vehicle, a Lexus LC 500 convertible is incredible as well!
STUNNING MACHINE S5 Cabriolet
I can write an entire diatribe about this car but I'll keep it simple! If you are looking for a luxury, convertible, look no further than the S5 cabriolet. I looked at the C43, M440i, this car, IMO, is the BEST value for the money! It is an absolute beast in the performance department, the options that come with this car for the price are unmatched and of course every single detail is perfectly executed!

⭐⭐⭐☆☆ (3/5 Stars) I had a great initial experience with
⭐⭐⭐☆☆ (3/5 Stars) I had a great initial experience with Highline Autos. The transaction was fast, smooth, and professionally handled. The team—especially Zuhair, the owner, and the young Ghalib—was responsive and knowledgeable, making the buying process straightforward and low-stress. Their professionalism and business reliability stood out during the deal. However, about a week later, I was disappointed to discover that the tires on the car I purchased were leaking. Upon inspection, it turned out that plugs had been used as a temporary fix rather than properly addressing the issue. This was unexpected and concerning, as I had hoped for greater transparency regarding the vehicle's condition. While I appreciated the efficiency and service during the sale, I hope the team takes this feedback seriously and ensures that future vehicles are fully inspected and represented. I’d encourage potential buyers to have a thorough inspection before finalizing a purchase.

My truck buying experience
I really appreciate the way that Anita Ford handled my buying process. It was with such a great service. She didn?t leave any stones unturned. Even the finance department went above and beyond to make sure that I had what I needed when buying my truck. I just want to say thank you to each and everyone one who took the time out to make this happen for me.
