I had the best experience buying my new Trax.
I had the best experience buying my new Trax. Craig Winger was absolutely amazing. He is very personable He was great about what I wanted and did not try to persuade me in any way. Just a great guy and you felt more like he was friend than a salesman. The whole Lynch family was great. Tom and Dan were great also. Just a great experience for buying a vehicle, the best I have ever had. Craig thank you I Love my New Blue Trax. Would totally recommend Lynch for your next vehicle purchase. 10 stars and more
