Went the extra mile
I had an excellent experience with this dealership from start to finish. I bought the car from out of state and Jonathan De La Cruz did a walk around for me, had the car in perfect shape for me, arranged to have a car pick me up at the airport, and then Niello literally went the extra mile (143 to be exact) to get me where I needed to go with my certified pre-owned MINI. Very happy with my treatment and all employees I encountered. Though I hope to never have to go 1000 miles again to get the perfect car—I’d be happy to work with Niello again.
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 had a great experience buying my car from Sports Cars
I had a great experience buying my car from Sports Cars International. They offer excellent customer service and well-maintained vehicles. Highly recommend this dealership to anyone looking for a used sports car!
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!

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.

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!

A pleasure to buy from
I had the pleasure of purchasing a pre-owned classic Ferrari from the team at McLaren Boston, working primarily with Jonathan, Bob, and Corbin through the various phases of the deal. They are consummate professionals, and will go to great lengths to make a customer happy, as they did for me. Jonathan's assessment and description of the car over the phone and through email was accurate and honest, and the car presented better than expected upon seeing the car at their facility in person. Speaking with Corbin at length on their shop floor, it is evident that his expertise extends far beyond the realm of late model exotics, and is backed by contacts and experience with some of the finest classic and exotic names in the northeast. Negotiation on price and terms was a breath of fresh air. Very straight forward, and resolved within a matter of minutes without pretense to very fair terms, having been searching in the market for the past year with a more intensive focus the past six months. Jonathan also put forth the extra effort to locate and secure some invaluable original documents and historic records for the car, which was a most welcome surprise on the day that we closed the deal after a successful PPI. Bob made the deal easy, quick, handling all aspects proactively. To all of them, that I am thankful. I wish the McLaren Boston group much success in the coming years.

Sales people are very personable and knowledgeable. Hutch and Jr. are my go to sales people and would recomend them highly.. Both make sure you are happy with your purchase and understand all the aspects of the car. Ryan in finance is also great to work with. This is the third auto that my family has purchased and we would not go anywhere else.

Top Shelf - Top Notch ... Fantastisch!!
From spotless floors to genuine concern, iAutohaus is far beyond a dealership or service shop. Wesley, Joann, Christopher, and the Staff - they are like family. What a fantastic experience. I sent technical questions about the BLUETEC diesel I found in their inventory. Had an answer from Wesley in my e-mail within minutes. Scheduled a flex-time appointment and was greeted with impeccable service, superior knowledge, elegant style, and genuine authenticity. Can't ask for more from a dealership or its management. This MB will be the first of many future purchases, no doubt. Well worth the drive from Four Corners to Tempe!!! Have already recommended the dealership to two family members and several friends. All were impressed with the purchase and the more than fair price. "Es war ein tolles und unvergessliches Erlebnis. Sehr Gut!!!"

Extraordinary service in an emergency
My husband and I were recently on an extended trip from NC to Alabama to Michigan and upstate NY. Our S550 decided to break down just outside Lansing. The airmatic suspension failed and car was not safe to drive. Lucky for us we were only a few miles from this dealership. We called and Eric Shier took us right in when we arrived. Had the car assessed by Ali in short order. He was able to order the parts and had us back on the road in two days - no quibbling about not having time to get to us till next week, etc. And Ali even helped us transfer our luggage to the rental vehicle and reassured us that he knows his way around the S class. We count ourselves very lucky to have had that breakdown near your dealership. Excellent care from both these gentlemen. Might even have to visit family in Michigan the next time we are in the market for a car. Thank you

Vic took his time with us, did not rush, and had an answer for all of the questions we, my dad and I, had. He was patient and understand my needs. He did not try to pressure or convince us into buying anything. But I fell in love with the red Audi A4 2018. I was in and out in no time and the paperwork process was swift and simple. I couldn’t be happier.
