Thank you George Ovies
I received a letter from Nissan alerting me that my current lease would be expiring soon and to come in and review my options. I’m very pleased with the T&Cs of my new lease and my 2024 Altima I drove away with in just one meeting Thank you George for listening to my needs and providing this beautiful 2024 Altima
"THE" GMC Truck!
I have a 2023 GMC Sierra 1500 Denali with the 3.0 Diesel engine. I have 20,000 miles on it at the time of writing this. Never owned a diesel before and now i don't think i will own another one without it. I LOVE the engine in this truck. Only complaint would be that it likes DEF fluid while towing so pick up some extra DEF before you head out to tow something. Put about 8K miles on it this summer without adding any DEF fluid. seems to use a little more in the winter or when towing. Very quiet for a deisel and the fuel economy is awesome. Driving 70 mph down the freeway this truck gets about 30mpg, Drive 55mph on regular highways and this truck gets almost 40mpg. All around driving for me is about 26mpg. I used to fill up twice a week with my gas motor and now only once a week. Wireless Apple Carplay works great and the voice texting and mapping is a big plus. I also have the new SuperCruise feature which is awesome. Get on the freeway and set the supercruise on and the truck drives itself until i get to my exit (about 28 miles from home to work). Bose stereo is out of this world and all the storage is great to. I have a swingout bed toolbox, aluminum roll up tonneau cover, Lighted black GMC front emblem, Gloss Black 22" wheels, All Black decals and my dual exhaust bezels are black as well. I rotate the tires and change the oil every 5,000 miles. Couldn't ask for a better truck. Might get the ultimate next time as that has the messaging seats which i kinda wish I had.

I had a great experience working with Jason Archimede
I had a great experience working with Jason Archimede from start to finish. I wanted to upgrade from a sedan to a 3rd row SUV and he took the time to ask questions and listen to what was important to me in a vehicle. I did not have a specific vehicle in mind when I began my search so I appreciate all his time, effort, and flexibility to help me find what was right for me. He is very knowledgeable and I absolutely recommend working with Jason. I have nothing but great things to say about Jason and the staff at Boucher Nissan I met among the way. Thanks Jason!

I had an outstanding experience working with Ty on my recent vehicle purchase. He was consistently responsive, knowledgeable, and never pushy throughout the process. We don’t purchase new vehicles often, but when the time comes again, I will certainly return to Ty. I highly recommend him to anyone looking for a straightforward and positive buying experience.

Had the pleasure of having Nick Majeske provide us with an unbelievable experience of buying a new car. From start to finish and even after we purchased our car, his support and genuine desire to make sure we were satisfied did not go unnoticed. What really stood out to us was throughout the process, Nick was transparent and honest, which I greatly appreciated. He kept us informed every step of the way, and there were no surprises or hidden fees. His professionalism and integrity are truly commendable. We could not be happier with our purchase and overall experience throughout it all, and we would like to think this was in all thanks to Nick.

Lynch Mukwonago - The place to go
I started here as a service customer, since then, I have bought 2 vehicles from the Lynch group. Both buying experiences were nothing short of amazing. Such a knowledgeable, low pressure buying process both times, I’ll never go anywhere else, Mopar or no car!
