Purchased pre owned with 56k miles. Everything seems to be great thus far. The only thing is I’m not sure the AC actually works as I normally keep it set to the “Auto” function. And when the temperature got up a little warmer than normal it didn’t seem to make the adjustment.

My overall experience at Dave Sinclair Lincoln has been amazing. My sales rep Dee-Davis. She did such an amazing job with the whole process. Great communication. Dee got me approved in minutes and I was out the dealership just as quick. I truly recommend purchasing a vehicle from this dealership and also Dee-Davis.
One of the most fun SUV’s I have driven!
The vehicle was great EXCEPT for the shifter which was the worst type EVER that GM designed!! I had family that could not figure out how to use it!!

When I purchased my dream car Genesis GV70 from this
When I purchased my dream car Genesis GV70 from this dealership I noticed how well kept the service area was. I only take my car here for service because it is professional, clean, organized and the staff is amazing. They do great work and often have you in and out in less time than expected. Josh and Brad have been so helpful. Their knowledge and experience is much appreciated.

Our favorite car in over 4 decades of ownership.
We love this car. I've had Lincolns including the Navigator, high end Chrysler vans, "luxury" Fords like the Eddie Bauer Expedition and Mercury Mountaineers and this is by far my favorite vehicle. The Enclave projects luxury and backs it up. We have the Premium edition. The ride is excellent and far outclasses other SUVs we've owned which rode more like trucks. Plenty of room and a 5 star safety rating make it ideal for toting around the Grandkids. We went AWD for Michigan winters and plowed right through deep snow. A little more power and a little better gas milage would be nice but it's worth the trade off. 18 mph city is better than the Buick Regal Turbo we replaced and this car rides better too. I'll take the 23 mpg on the highway. As a 70s rock and roller and 45 year radio industry veteran, I love the Bose sound system. Especially when no one else is in the car! This is by far my favorite overall vehicle in 47 years of ownership. And yes the Kids and Grandkids give it 2 thumbs up!

My experience was outstanding with Mathis Motors and
My experience was outstanding with Mathis Motors and their sales team. The salesman Jacob was incredibly responsive and knowledgeable. He responded nearly immediately and was able to work the deal in the moment. We were able to set it all up in 30 minutes or less. The SUV is exactly as described and was cleaner than any used vehicle and most new vehicles I’ve ever bought. I appreciate all they did. I would and will give them my business again.
Awesome riding suv. ❤️
Excellent riding SUV. I would highly recommend this SUV. Not bad on gas for a large vehicle. Plenty of space. Very quiet!! Lots of room for big people. ❤️

Everyone was nice and the place was extremely busy. We worked with Nick who was working with 2 sets of customers at the same time, he did a pretty good job of handling both. We test drove a truck and tried to work a deal, but it just did not get down into our price range.
Luxury that delivers
I absolutely love this car. While being priced on the high end, this is a luxury car that delivers. With 310 horsepower, 9 cylinder transmission, and luxurious interior appointments, this car delivers power and can definitely leave you feeling spoiled. The only issues that I have seen are really minor. The fuel door, when opened, can actually dent the body of the vehicle. The interior shade on the moonroof is a manual latch, not mechanical. It simply seems a little cheap compared to the rest of the car. My model is an Avenir model, but it does not have the advanced cruise control or the self parking modes. It did not have a significant price drop for not having these options and I am not sure why an Avenir model did not have all of the options available. I had to buy it during the chip shortage and took what was available. Altogether, this is the nicest car I have ever owned and I am very pleased!

Great Honda dealership
Jeff Reed provided great service. He is attentive to what we want to know and goes the extra step to make sure he provides that. All the people we spoke to were professional and friendly.
I love my Buick Lacrosse
This is by far the best car for your money, I bought this car used with almost 40k miles and now it’s at 110k miles in about a year and a half. I drive 100-300 miles a day and this car gets around the same gas mileage as my old Hyundai sonata. This car is driven through heavy traffic in Washington DC and the rural countryside on a daily basis and can handle just about anything. This car drives and feels like a Mercedes S class. I travel around the area and I couldn’t think of a more comfortable car to do my job in. I never have to worry about reliability. The only con with this car is that an oil change is about $120 wherever you go (DC Area) and my fog light was knocked out by heavy snow ($25 part). If you’re researching you should definitely buy this car.

I bought this used with 26,000 miles in the spring of 2024. I love the styling, interior, and value. My only complaint is that the angle of the infotainment display can make it difficult to see due to reflections, especially in bright sunlight. I love the AWD option, it adds to stability - even in dry conditions. The remote start is handy in cold weather since I now live in an apartment and no longer have a garage. Performance with the optional engine is more than adequate.

I bought this car 9 years ago as an ex hertz car.
I bought this car 9 years ago as an ex hertz car. It had 24000 miles and now it's only got 52000 miles. The reliability is bulletproof so far nothing has ever gone wrong (touch wood). I've owned 33 cars and this car has Honda/Toyota build quality and reliability. The downsides are I find it very thirsty, I've never managed better than 22mpg in mixed highway driving. i find that the car is quite gutless but it's fit for purpose. The resale on these is worthless so I plan to keep this car until it dies. I have other cars but this is still my daily driver.
