Went to O’Fallon Buick GMC to look for a truck. Pulled up and met Nick D. At the door. He was very easy to work with and did not try and sell me a bunch of extra crap like alot do. Very knowledgeab Pulled up and met Nick D. At the door. He was very easy to work with and did not try and sell me a bunch of extra crap like alot do. Very knowledgeable about their products and services and walked me through it all step by step. He made the process easy and I would do it all over again in a minute. They beat all the other dealers around on truck prices and if you do your research like I did, you will see it for yourself! More
