2021 GLC300 4matic
I absolutely love this compact SUV! Coming from a Subaru Outback, this is light years above and beyond for same year. A quiet cabin is my top want for buying a car. This cabin is quiet and relaxing inside. I’m tall and there is plenty of room. The seats are incredible! Can’t wait to take it on the roads in winter.

An overall great service experience when ever my out of
An overall great service experience when ever my out of warranty Lexus needs service. Comfortable and clean lounge areas with plush chairs for waiting and plenty of connections for laptops or phones if you need to do some work while waiting. I always work with Darryl who does an exceptional job for me. He’s very professional as well as being personable. Ask him anything about the work that needs to be done and he always has the correct answer. Darryl is one of the reasons I keep coming back to Elgin Toyota
Exceptional Comfort
I have had this vehicle for only one month so have not developed much experience with it. I did take it on a 1400 mile trip two days after purchase. It ran well, was very comfortable to drive, made for a very easy trip, was great on gas mileage, and it is very quiet inside the cabin. Seat comfort is exceptional and this, being our first experience with heated seats and steering wheel, was most enjoyable.

Eddie
I bought a Lexus LX570 from Greg. I was nervous as I never bought a car without driving it or over the internet. They delivered the car to my home and offered me more than a fair trade on my Mercedes. I was more than happy with the LX and Greg was great. I would not hesitate to trust Greg's word. It was a great buying experience and they did not disappoint me. I highly recommend this dealer.
