Very knowledgeable and professional
Very professional and knowledgeable of my Jaguar...I will always come back...service is great ...price is affordable..recommend anyone with a Jaguar to get service there when needed
Love at first drive
I love my 2020 x3m. I will own this until the wheels fall off and replace it with another x3m. The gas mileage at 19.5 miles a gallon is the only bummer but it’s well worth it.

I recently purchased a 2021 Ram 2500 at Sports Cars
I recently purchased a 2021 Ram 2500 at Sports Cars International, and the experience was flawless. Great customer service, knowledgeable staff, and an amazing truck. I’m very satisfied and definitely recommend this dealership to other buyers.
Awesome!!!
I’ve owned a 2020 x3m competition since the month they were released. First let me knock out rough ride thing. If you ride on the stock Conti summer tires all the time, yes it can be rough. I switched to to Michelin all weather after 11,000 miles and it made a huge difference! A much better more comfortable ride Side note: when I would swap Conti to winter tires also a huge difference! The stock summer tires that come on the car are incredible for handling on a track which the car was made for but, the car feels much better with Michelin all sports all seasons. This car makes me happy every time I drive it ! So much fun to drive!

The in and out of car dealerships.
They asked US what WE wanted and OUR budget. Then they pulled each car up to us while we waited in the showroom. No pressures. No price haggling. Superstore inventory on their massive lot. No experience in repair rating so average given. Overall 4 stars due to no one being perfect. They came very close. We will recommend Velocity to anyone needing a near new vehicle.
Sedan vs SUV
Absolutely love this SUV. Had a M340i and it was quick, but this X3 M Competition is wicked. Love the quickness and the firm ride. Glad I made the switch. Lots of talk about the firmness and the rigid handling, but try one and see for yourself.

Pace is the best and most hard working salesperson in the business! He got me a better deal than I could imagine - found the right car at the right price - he is an angel for sure and very friendly, knowledgeable and goes above and beyond to help you get what you want! Very interesting person and truly cares about providing the best customer service! Surpasses the average sales person by a 100 fold! If you want a good deal - call Pace!
A fun and enjoyable ride!
Yes, it’s crazy powerful but you can definitely tame it to be a fully enjoyable ride for everyday use. I look forward to many years with my new X3M!

SUV Upgrade
We upgraded my SUV and traded in at this dealer. The first person I spoke with, Shelby, was super nice. The next person we worked with, Caden, ended up being our sales person. He went through a virtual appointment with us since we were over an hour away. The next day, we drove out to the dealership and traded in my current SUV to a newer one. Caden was also super nice and apologized several times because another client showed up early, overlapping our appointment. We appreciated having a sales person that was down to earth and welcoming.

Positive experience
I had a very positive experience with my sales person Amy Mattick. She followed up to make sure I was comfortable with the features on my new x5. I have bought an x5 before from the dealership and have always have good experiences. I would recommend Minnetonka BMW and Amy Mattick.

⸻ Zach was very informative, knowledgeable, and quick to respond. I do have one suggestion: if you’re selling EVs like Teslas to out-of-state customers, it would be helpful to deliver the vehicle with a full charge. Since Tesla’s Supercharger network cannot be used until the app is properly set up, it can create a challenge for first-time handoff. That said, I’m overall very happy with my purchase and appreciate the great service.

This was the best experience I've ever had with a
This was the best experience I've ever had with a dealership. My sales associate AJ, was truly an expert on not only the vehicle that he showed me, but on the company as a whole. He was able to demonstrate how to use all the fancy safety features and explain what they did, and answer any questions I had with confidence. He was so friendly with both my daughters, and went out of his way to make sure I was comfortable. AJ was very open and honest about all the different dealership fees that would add on to the total purchase price, and explained what they all were. He was quick to respond to any messages, and did a great job of keeping my needs and wants for the vehicle in mind when showing me different options. They gave me a good offer on my trade in, even though it was less than I owed on the vehicle. He and his manager Paul were even willing to come up on the trade in offer, but my vehicle has a bad accident from the previous owner on the carfax. Paul explained his reasoning for the offer which came directly from KBB (another dealership tried to offer me $2000 less with no rhyme or reason). I know dealership fees can be frustrating, but I think the fees at Volkswagen Brandon are fair compared to other dealerships in the area. AJ did definitely do his job as a car salesman and try to upset me, offering me finance options for New vehicles, but was completely respectful when I told him we weren't interested in financing or a new vehicle. He didn't keep pushing, instead focusing on trying to get me in a vehicle that fit our budget and that I loved. I absolutely adore my new 2023 Tiguan, and I 100% recommend Volkswagen Brandon for your vehicle needs.
