Sure pleased with my new Cadillac XT6 and the really positive experience I had with all involved with the purchase process at Coulter Cadillac in Phoenix. Briefly, live in southern California and found positive experience I had with all involved with the purchase process at Coulter Cadillac in Phoenix. Briefly, live in southern California and found my new car on Coulter’s website. I planned to trade-in previous car so had concerns regarding the trade process and transaction with a dealer 250 miles away. Sent message to Coulter through their site, had a response within an hour from Joe Augusta in sales. The purchase outcome was outstanding - I’m happy. Sales-Joe and others insured I got a very fair deal and the process was transparent, informative and sure created a high degree of trust with me. Would recommend Coulter without hesitation. More
