They found the vehicle I was looking for.
They found the vehicle I was looking for. The purchasing process was fast, fair and comfortable. Will use them again with next purchase. Highly recommended.
So far so good!
So far so good! This truck is the nicest truck I have ever driven. The stance, ride comfort and options are top notch. I went from a 2023 High Country that was having drive train issues but had all the creature comforts that you would expect in a top of the line truck. With the lack of confidence in that particular models 10 speed transmission issues, it became necessary to reestablish my confidence in my General Motors product.

Got a used car, good experience
I had been looking for a Highlander for over a month and saw a nice one at Greenwood. I have talked to a number of sales people and by far Tom was the most down to earth. There was no pressure and he did what he said he would do. He helped me get a great rate for my loan and the experience was sooth and relatively easy. I would recommend buying from Greenwood Automotive.

Five Star Service!
I drove right in, the Service Associate that greeted me was very polite and explained exactly what was going to be done, as I waited for my vehicle he came to check on me and asked if I had any other questions or concerns, it was a great experience and I will certainly be returning to Transwest GMC for all my service needs

Gregory at Castle Chevy GMC is the automotive wizard we
Gregory at Castle Chevy GMC is the automotive wizard we all need! When my wife’s 2023 GMC Yukon XL needed some TLC, Gregory didn’t just fix the issue—he played detective, keeping it an extra day to crack the case like a vehicular Sherlock. And as if that wasn’t enough, he sprinkled some magic dust on a couple of minor, non-essential fixes that were the cherry on top of this service sundae. Professional, communicative, and an absolute delight to work with, Gregory’s the guy who makes you wonder why all car repairs can’t be this fun. Highly recommend him and the Castle Chevy GMC crew for service that’s smoother than a Yukon on cruise control!

Rafeal was my contact there and he was great.
Rafeal was my contact there and he was great. He went above and beyond to communicate share photos and video and was very transparent. As a matter of fact the whole process and everyone was easy to work with. Not the dealer where sale and sale manager go back and forth to do some crazy negotiating. Open transparent and fair dealing. Rafeal was an advocate throughout and in and out with anew car well less than an hr after trade in paperwork

I was here at the dealership a few months ago and I traded in my 2010 challenger on a 2014 challenger. The new one I purchased was an absolute gem. It only had about 600 miles on it. I thought “no way will this get approved” I’ll have to drive two hours back home without the new vehicle. Well I am pleased that I had Vincent and Kurt to help every step of the way. Between the two, they got me the best deal possible and I got exactly what I wanted. Never any pressure at all from anyone. The whole team there was exceptional to work with. I couldn’t have asked for a better car buying experience. Thank you to everyone. I definitely recommend going to Omeara. I will for sure be going back when I need to purchase another vehicle. Bill

Looked for a low mileage Acura TLX or TSX for six months and I found this car near me. It was nicely detailed and looked well cared for from the posting on Cars dot com. The sales rep called me very soon after my initial query. The entire buying process took an effortless one hour and I was on my way with the beauty,
