Quiero agradecer a Alain Hernandez por la excelente
Quiero agradecer a Alain Hernandez por la excelente atención durante la compra de nuestro vehículo. Especialmente a Alain Hernández, quien fue la persona que nos ayudó en todo el proceso. Desde el primer momento fue muy profesional, atento y transparente. Nos explicó cada detalle con paciencia y siempre estuvo dispuesto a responder todas nuestras preguntas sin ninguna presión. Hoy en día no es fácil encontrar personas así, que realmente se preocupen por ayudarte a tomar una buena decisión y no solo por vender. Sin duda, recomiendo a Alain Hernández si estás buscando comprar un auto con confianza.

Bryce took care of me in no time at all, great car and price! Thank you!!! Will recommend to everyone!
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.

I was choosing between several crossovers and visited different places. In the end, I bought the Outlander here. Probably because everything went calmly and without extra pressure.
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.”

I had an amazing experience purchasing my used 2020 Jeep
I had an amazing experience purchasing my used 2020 Jeep Cherokee back in May 2025. The salesman, John Griffin was absolutely fantastic! From the moment I shared my requirements and budget, he worked to make it all happen. He secured a great financing rate and found the Jeep of my dreams. I couldn't be happier with my purchase and I absolutely love my Jeep! John, your professionalism and salesmanship truly stood out, making this car-buying experience one of the best I've ever had. Thank you once again, John, and the entire team at Suburban Cadillac of Plymouth, for making my car-buying dreams come true. I will definitely be recommending your services to friends and family.

I had a great buying experience at Motor Werks. My agent Scott was professional, helpful, and guided me through their process. They have a policy of trying to get you in and out in an hour which is excellent. There is no need to waste time at a dealer. I applaud them for caring about my valuable time.
