Shop Dave Taylor. The best price, the best staff!
Dave Taylor dealership was outstanding from day one. I personally dealt with David Smith, who is professional, courteous and understanding from the word go. From the moment I first met him on our test drive to the final signatures. He was awesome. My stepson was moving into college so we had a lot of things we had to work around at that time. David Smith took the time out of his day and helped us by taking my wife back-and-forth to our home and also dropping off a dolly at our home. Not only did they gave me a GREAtT PRICE for a Chevy Camaro. It beat the price of all others. I priced that year with those miles on it and every other dealership had them at the least 2 thousand dollars higher than Dave Taylor’s price. They are real, down to earth people that do not have that fake friendliness. They were true and sincere and HONEST! I am 53 years old and it was the best car buying experience I’ve ever had. So thank you Dave Taylor and thank you David Smith!
2019 Buick Envision has vibration an shaking issue
I’ve had my 2019 Buick Envision since January of this year (2023). We were traveling from GA to MS today and for the first time ever after hitting a bump two different times (a couple hours apart) our vehicle started vibrating and shaking terribly. Very concerning.

For a car made in China, with their reputation for putting out shoddy products and looking at their buildings and roads that's falling apart as we speak, I was totally surprised at the quality built into this car, not knowing at the time of purchase that it was made over there, which would have made me pass on buying it. But we are talking GM here, that built the plant in Shanghai, who took every part over there just to use their labor only to assemble it, and they did an excellent job. I figure that GM pays them better than all other jobs in that country and they don' t want to lose that job, so they do the best that they can when putting it together. We are at 105,000 miles now, and did all the oil changes and did go through the hundred thousand mile checkup and all fluids changed, and it has yet to have anything to go wrong with it except for changing out the 5 year gel filled very expensive battery *at 5 years on the dot, and the second set of tires. Even still has the original front pads on the brakes, but due to my real easy driving and feathering them coming up to stop lights, trying not to let the stop/start system engage at full stop, and have been doing an excellent job in timing lights and breaking one law by doing 'rolling stops' at stop signs with no cross traffic in sight. I'm a person that drives a vehicle until it rots down, like I did my '84 Toyota diesel pickup that I put over 800K on it until finally the box frame under it rusted in two, forcing me to park it forever, with the engine still running in it. And with this car I'm shooting for the same mileage before it falls apart just from so many miles on the body.

Ryan did a GREAT job as did everyone else.
Purchased a 20yr old Nissan from Ryan, he and the team there gave me as much information and the condition of the vehicle as was possible based on the age and of course based on the age the car does have its issues which I had expected, but Ryan did a great job of working things out and as I arrived really late he and the necessary people to finish a deal were there and ready to help. I picked the car up the next morning with a full tank of gas ready for my 300 mile trip home. They gave me a great deal on the vehicle, far below what they were asking all said and done out the door.
Bad roof over my head
I purchased this car new i have the panoramic sunroof. It leaked the year after I bought the car was repaired under warranty. Last month the roof started leaking again. Cost a fortune to fix as i also needed the roof shade as that was water damaged. I love the car. But do not get one with a panoramic sunroof.

What a nice surprise.
I unexpectedly wound up leasing a 2022 Buick Encore GX. I have been very happy with all of the features and performance of the vehicle. It is peppy, handles great and is quite comfortable. A small step down in size from a Chevy Equinox and it has worked out extremely well.

He took all of the things I felt I needed into consideration and was patient and kind with my indecisions. I hadn’t bought a car in many years and he made it practically painless! I will be telling people to go to Pundmann! Thanks so much!

We love this car. Drives well. interior has a luxury car feel. my husband and i are both tall and a little heavy and there is plenty of room in both front seats for us. you do need to have light weight, slightly shorter friends for the back seat. the only drawback i can even think of is there is not a ton of room for multiple suitcases if you are picking up another couple at the airport. other than that, this is a great auto. we have had it for 3 years and have not had one single problem with it!!!

The hidden gem Buick Encore GX
I know that here in Northern California, Buick isn't a very popular brand, but that means I was able to get a stunningly good deal on my new '23. I traded up from a low mileage '18 Buick Encore (not GX), and at the time of the transaction, it had a remarkable trade value. My dealer did a outstanding job on pre-sale prep and delivery. My sales rep answered my every question. I enjoyed the prior vehicle, and feel this new one will give me the same kind of driving experience. My added safety feature is the front accident/pedestrian avoidance and lane keep assist. I haven't had to use either yet, but feel good about having them aboard. This Buick strikes me as a hidden gem, full featured but still available at a price point that blows the other comparable Asian built imports out of the water.

Had bought the 2021 Buick encore gx AWD brand and up to this point I've had 0 problems with the car. Handles great and get pretty much get in to any tight spot that bigger vehicles would have a hard time on doing.. Great on gas I save tons of money on gas alone so that by it's self is a huge plus.! I'm a big person being 6'3 and I have no problems sitting comfortably in the drivers set - of course my set has to be all the way back so can't have anyone sitting behind me unless they wanna get squashed.!! Sharp little car that performs pretty great and being from WI it actually drives pretty great on bad winter roads with the AWD on.. My overall view of this car since I bought it new is that it's an excellent car that most definitely can be trusted very reliable and once again you can pretty much fit into any small space and making tight u turns is a breeze for this car..!! Perfect car for City driving I'm happy I went with this car. Being a bigger person and being 6'3 I was pretty surprised at how comfortable I was driving this small compact SUV...

I bought 2014 Premium AWD used w, 30k miles and odometer now reads 179k. The car has been very reliable , I have replaced the water pump, timing belt, and done brakes and oil changes, I also fixed the manifold/valve cover issue. These were all normal Repairs . I am pretty good with maintenance, so that is key w this car. If you just drive it, don’t change oil or fluids then like any car you will have problems . This one has been very good .
