A one-of-a-kind car salesman
I was referred to Anastos by my aunt, more specifically to Mourice. The first night I was there, he found me the perfect car. Exactly what I was looking for. Then, he proceeded to do everything in his power to make my payments affordable, being that I'm a full time student and cannot work as much as I should. I came back a few days later to inquire more about the vehicle to find out that not only did Mourice accomplish exactly what he said he would, he went beyond that. The loan payments... including a 100k mile warranty, came to be 2/3 the price of the exact same car without a warranty from a different dealership a mile away. Aside from Mourice giving car salesmen a great rep, he was an all around great guy. Before we even spoke of the car, he displayed genuine interest in my schooling and plans for life, showed me some of the owner's specialty racing cars, and invited my mom out for pasta and wine. Which I approve of. Needless to say, if you want a car.... You want Mourice.
Nicest, best performing truck I've ever owned
My truck has a great appearance, inside and out. It is a pleasure to drive; and rides and performs great. It is the best truck I've ever owned.

Go see Maurice....he has SUPER POWERS!
If Maurice were a super hero, his super power would be making great deals happen. He was friendly, helpful, informed (and don't even get me started on his accent)! I never once felt pushed or pressured. I am 100% convinced that the great deal I got would not have happened without Maurice. Aside from that, it is a rare salesman who makes you feel like he is really ON YOUR SIDE. I'll keep it short - he's earned my trust and that is the ultimate compliment I can give.

Buying a car is stressful overall but Mr. Lee McGee made it an easy and fun experience this time around for me. He was very helpful, going above and beyond, trying to do what he can to make things easier for me. He has a lot of knowledge about vehicles and how to go about saving money! If you’re looking to buy a car at Boucher, Lee is your guy!
