steven horton.....just beyond sad your sales manager nd team wont own up to the service light for the oxygen sensor going off and fixing it when I just bought the dang truck 2014 chevy Silverado crew cab. day I got it the sensor(s) shot off. freaking pathetic they giving me the go around making me responsible due to there service people not doing something right first time. very unhappy and I am giving proof along with the worst rating I can on any social site for this company for there shady acts and xxxx poor communication efforts to fix the issues I been having. I'll never recommend anyone buy from you guys if anything I am determined to make sure so many know not to go through you guys due to your acts and selfish ways. I'd post picture of what tripped but will not let me. ended up having emission leak with vacuum leak and cylinder 3 misfiring . within a day of purchase. great service team and covering up faulty equipment

Great Service and Easy Transaction

Reviewed by Andrew Massey in Chelsea, MIOctober 07, 2020

Recently bought a hard to locate Miata MX5 through them. I had to travel a good distance to get the car and they were transparent and very fair about the pricing so we had the deal completely agreed to before I arrived. My sales person picked me up at a local airport and we had the paperwork done very quickly and I was on my way. Excellent customer service and a particular shout out to Leo Moskowitz.
