Great experience. No pressure. Derek Welch was a wealth of knowledge who gave us extra tips as he owned the same model of car we purchased. Great selection of non VW. Would buy another car from Mastria VW in the future.

Emmanuel helped me get into a new car, was extremely professional and the process was not as long as I was anticipating. The dealership was open to negotiation and met my bottom line.
Beautiful and comfortable car
It is easy to navigate , good for gas, quiet but still shows the work of the engine. Warms up quickly and has luxurious look.

The Perfect Luxury car
I purchased the CT6 Luxury AWD new in 2017. I haven't had any issues at all. I love the double sunroof and the 360 camera view. But what I am really upset about is GM discontinued this model. It is an awesome driving car and I won't be getting rid of it anytime soon.

Excellent service and amenities
Prompt, courteous service. They do not try to push extras on you if you say no the first time. On time for appointments.
MOVE OVER M.BENZ
I purchased the car new and have had it for 6 years, it has been nothing but awesome in many ways. The styling has endless elegance and will always be a good looking car. Being at "this time" possibly the last of the BIG BODY Cadillacs it will remain special in many ways. It is a great driving car with the combination of AWD ultimately makes it a year round car for my location.

Seems to be a decent dealer.
Seems to be a decent dealer. Sales people are respectful. I'm trying to negotiate on a new 2023 Ford F-350 4X4 with 7.3 gas V8 and they seem to be a bit reluctant to bite on what I consider to be a fair OTD offer, especially since the vehicle may be subject to some lot rot due to the length of time there on the lot and not sold as of yet.
Car size is good, considering the market for sedan
Plenty of room. I used the controls on the steering wheel. Never on console, sometimes on screen. Seldom take eyes off road. Had twenty months left on my XTS bumper to bumper . Next car was going to be CT6. I don't know what Cadillac is doing with sedans. There were no CT6 in Tampa had to go to West Palm but the CT4 and 5 were too small. The screen on the CT5 looked like it was slapped on top of dash and sun roof left something to be desired. Cadillac and sedan?????. looks like Electric in the future ?????

My family has bought 35 cars from carmax, never had an issue.We had some issues with some of the cars but they took care of it right away. What gained my respect for carmax is that we bought a car a HYUNDAI ELantra 2012. DROVE THE CAR A LITTLE OVER A YEAR. Went to trade it in and we found out the car was in a bad car accident in the front, and that's why it was pulling to the right. We were never told that this car was in an accident. We were told that it never was. Immediately they paid off our loan and put us in another new car. That's a good company. Therefore in my opinion they are awesome
Love my Red Shiny Cadillac
This car drives like a dream and the 3.6L Engine gives me that burst of power you really want when entering a fry. Love the Apple Play features that put all the apps from your phone on the screen, allowing me to listen to my audio books. The turn by turn navigation system is really nice and the screen location is just in the right place.

Carmax is transparent
Car Max seemed very straightforward and transparent. Pricing is no haggle set pricing. I appreciate the excellent customer service and they appreciated my time. Carmax has simplified the process.
Pure Comfort
I recently purchased a 3.6 Premium Luxury CT6 with 30k miles, had the transmission shudder after about a month of owning it. Since it has a 100k PT warranty I took it in and the dealer flushed the transmission and replaced it with a different brand, works perfectly now. Took it on a 4000 mile road trip over the holidays. Outstanding ride, 28mpg avg doing 80mph. This car is a joy to drive, plenty of room, plenty of power and excellent ride quality. Would highly recommend. I’ve owned this car for 6months now and have only seen 2 on the road.

Amazing...and American!
Recently bought a used CT6 w/2.0 Turbo (2018 with 39K miles). Have put only about 500 miles on it so far, but, WOW!!! This car is amazing! This car lives up to it's reputation as a builder of premium American luxury vehicles. My las t Cadillac was a 2000 STS...which was mediocre by comparison. It is soooo beautiful inside. I like that the screen is integrated into the dashboard. It's size takes a bit of getting used to, as my last car was a Mercedes E250. I test drove the 2.0 turbo and the 3.0, and found the 2.0 Turbo to be equally responsive but smoother. Exterior styling is simple clean and exudes luxury. I get so many compliments, heads turns and such. I love the Apple Car Play feature that projects what's on my phone to the in-dash screen. Recently did a road trip and got an AVERAGE of 33.4 MPG on the highway. I am getting 25 MPG+ around town. To me, that's pretty impressive for a car his size. In keeping with Cadillac's reputation, this car drives so smooth and quiet. Last time I drove a car this quiet and smooth as a Lexus LS460. At $30K less than the price of an average EV, it will take a lot of gas to make up the cost difference of those overpriced cars.

A Praise-Worthy American Luxuray Automobile
Having had my 2018 Cadillac CT6, equipped in the optional Premium-Luxury trim level, for nearly 3 years, I can honestly boast of its many attributes. It offers wonderful styling inside & out, the availability of virtually every current "high-tech" option conceivable, and has proven to be consistently reliable – and, while some may describe it as a bit “pricey,” it’s actually a relative bargain, when compared to its European competitors. The CT6 harkens back to the classic Cadillac sedans of years gone by, as its size, comfort, and luxury amenities remind owners and admirer’s alike, of many of those all-American classics. Although it's a pleasure to drive, even when equipped with the new and improved, 3.6L V6, the optional 3.0L Twin Turbo engine is recommended for those drivers who like a “little something extra” when depressing the accelerator pedal. With regard to performance, it is somewhat regrettable that an (optional) V8 is unavailable in the company’s “Flagship model.” This absence, I suspect, is a rather obvious "nod” to the so-called green energy movement that seems to have “infected” the entire auto industry, of late. In summary, if you’re looking for a full-sized American luxury car – look no further. The Cadillac CT6 “fits that bill, to a tee.”

We had an excellent experience working with Devin Thorpe
We had an excellent experience working with Devin Thorpe at Luther Used Car Company. He handled our transaction and walked us through all of the paperwork to finalize the purchase of our Dodge Ram. Devin was courteous, professional, and took the time to thoroughly explain everything while answering all of our questions. I purchased the truck with my 21-year-old son, and since this was his first time going through the car-buying process, Devin went above and beyond to make sure he fully understood every step. Thanks to Devin’s patience and clear explanations, my son will carry this knowledge with him for future car purchases. What really stood out was Devin’s passion for his job and the way he helped us through any rough spots with ease and kindness. We felt extremely comfortable the entire time and truly appreciated his professionalism. I would absolutely purchase another vehicle here again and would look forward to working with Devin in the future.

Absolutely Fantastic! Anna a well established veteran executive customer sales representative did an Absolutely superior job. She represented her dealership with honesty and integrity. We were very pleased. Thank you and everyone involved in our purchase.
Amazingly smooth, well-made
I'm trading my 2019 CT6 after two years. Have really enjoyed this car. There is no better highway cruising car ever, it's incredibly smooth but tightly built, not sloppy ever. Great gas mileage, very peppy, and beautiful. The electronics are very easy to understand. The only complaint- driver's seat too short, I'm 5'11", long legs, and I had a buy a bolster cushion. Otherwise, I've loved it. Trading up to a BMW 8 series for more excitement.
