Porsche 911
What a great sportscar...maybe a little expensive but after you have one you will agree that it is worth every penny...don't buy one as an investment, buy one to drive

Porsche owner since 1970. 2006 997 4 cab today
Owner of Porsche's since my first purchase new in 1970. 12 registered to me and another 20 or so I bought, drove on dealer plate when I was in used car business.M y 2006 997.1 Carrera 4 Cab with 30k on the odometer is one of the most dialed in cars I have driven. PASM along with the AWD helps keep this one glued to the road. The 4 is Wider than a 2 the S is not necessary. All season road runner. Top down warm weather, AWD for the rest. 😎

3rd time to buy here...
And will again in the future. We have always had great experiences with this honest, family run business. This was our first time to trade in on a vehicle here and feel like we got a fair price and a great value in the new car.
I think most of people here have not driven a Macan 3.
I think most of people here have not driven a Macan 3.6 Turbo engine with 400+ HP. This car is amazing you can't compare this one with other lower Macan models. this is the one to have.. We owned several Porsches including Cayennes turboS. This is a compact daily driving machine with Lot's of power and is fully loaded. The turbos 3.6 cost over $100K after taxes for a reason , Please don't compare this model with other low built Porsches for middle class, this is a High End Vehicle for a reason ...maybe the same as compare the Boxer with a 911 Turbo S.

The 991.
The 991.2 Porsche 911 really is the everyday sports car. Not conspicuous but also not mundane. With so many variants available, its hard not to find a 911 that fits YOUR needs and wants. The engine is sublime, the interior is refined and well built, and the cockpit ergonomics are unmatched. After driving a 911 (any variant), any other sub-150K sports car is just Meh. One of the underappreciated aspects of using this car on a daily basis is how easy it is to live with: the outward visibility is excellent, the tech is great, and the car is comfortable on long drives. When looking for your first 911, you should consider with a well-loved 991. I prefer the "Dot 2's" because of the turbo engine and the Apple CarPlay but the 991.1's have a charm of their own and shouldn't be discounted. One of the few drawbacks to any 911 is the road noise...you will have to get used to hearing those big tires hitting the road and if you drive on rough roads the majority of the time you WILL be annoyed (maybe look at a NSX or a C8 instead). Otherwise, you will not regret the ownership experience!

Good with caveats
Bought 2023 Macan T. I traded in my aging 911 for it. I did not buy another 911 because they have become too big and expensive. The Macan T is a fun car to drive if you are actively trying to drive it. The back seats are tight. The PCM is frequently confounding or crashes and won’t play any media unless you stop the car, turn it off then open the door close the door and restart it. The fit and finish is excellent. The upgraded seats are good. I can’t activate the around view monitor unless I put it into reverse. The dealer wants 300.00 to connect the my Porsche app on iPhone to the car. Porsche corporate is helpful and has normal humans that answer the phone. The PDK is fun and the exhaust has some fun subtle sounding pops. It’s like a refined hot hatch car but not really a great highway car. The base stereo is plenty good enough. Styling is top notch. Adaptive cruise works but needs supervision while using. The rear wiper appears cheap and flimsy. Should have been mounted from the top of the rear glass. The guages in the day are too dark not lit up and hard to see. The back up camera has poor resolution and has a strange perspective making it less useful. It’s a fun, clever designed expensive car with tech flaws that you have to overlook to enjoy the car. If you buy a slightly used one from a Porsche dealer you can get your warranty close to 6 years. Service is expensive probably to pay for giving you a loaner.

I saw the poor reviews and wondered about it.
I saw the poor reviews and wondered about it. But my experience was fantastic. Great people, very open and helpful. Honest. I'd definitely recommend them. I really don't understand the poor reviews on Car's. Google reviews them really well.
Macan Tyrbo
One of the most fun cars I have ever driven. The acceleration and handling are on another level than the X5M or X3M. It’s also practical and looks extremely sharp. Infotainment could be better - the PDK is lightening fast though. Exhaust tone is amazing. I can go on and on.

Purchased a used vehicle
Eric was my salesman and he was very helpful is closing the deal quickly and most importantly that worked in my budget. Arriving from out of the area he had the vehicle ready to show upon my arrival. USI Motors will definitely be my first choice for my next luxury vehicle.

Good fair deal.
We purchased a Jaguar from USI. We feel we got a fair deal and the salesman Eric was professional and personable. We would do business there in the future.
Just gorgeous
What can you say about any 911? The one I test drove was the S. It’s just the perfect sports car. Light, just enough power to go fast, not overwhelming. Comfortable, quiet, composed at any speed. The soft top is so quiet. Almost like a regular top. With the top down, you can still hold a somewhat normal conversation at highway speeds. Just the perfect car for a cruise or fast run on a sunny day.

2015 Porsche 911 Carrera 4S is an absolute gem!
The 991 series of the 911 platform is one of their best ever. This car is a joy to drive. I did not think that I could leave the manual 6 speed of the 996 series but the PDK transmission has exceeded expectations!
