Reuben Floyd was incredibly helpful in guiding us toward
Reuben Floyd was incredibly helpful in guiding us toward our 2024 Rav4. He was patient with some of our indecision but once we got to writing it up, he was very efficient and thorough. He was also a very pleasant person that we got to know. He was focused and really cares about people. He's a very valuable employee and we are grateful that he took such good care of us!
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.”

Smooth and Easy
Though I intended to purchase a used vehicle with a much lower sticker value than most of the cars on the lot I was treated with utmost respect and friendliness, from the office staff to the mechanic to one of the partners. They understood we had driven a couple hours amidst the coronavirus pandemic and worked quickly and easily with me to take the car home that evening. They honored the out the door price we had discussed prior to arrival and even shipped parts they were unable to return to Toyota at no cost to me.

Alex was my service advisor and he was amazing from start too finish. He was upfront on the possible cost and kept me informed along the way. Picked up my car and it has been running great. Thank you Alex and Spanos motors for taking care of your customers and being honest along the way.

Great company
First, I'd like to say I'll never buy from a dealer (other than CarMax) again. This process was painless and positive. If you go to Renton - ask for TYSON - he was great. Laid back, informative, and what I value most - not pushy or slick. I told him some of the things I wanted in a car and he came up with the perfect choice for me. The signing took about 30 minutes and I was done. They filled up the tank - put a pretty bow on the car when I picked it up - and generally made me feel important and valued. I can't recommend this company enough!

My old car broke down and towed it to Just Trucks for repairs. Bottom line is I ended driving my new car out of the lot just after a few days thanks to Charlie Rice. Just trucks arranged to pay off my old car loan and found a place to finance my new car. Staff at Just Trucks will treat you like family and take care of your needs. Thanks
