Worst service ever. We purchased a 2016 Buick Enclave back August 2015. On March 2016 we noticed that the interior chrome trimming had some sort of spots that don't come off. We took it to the dealer where we purchased it. They tried to clean the spots. Long story short they are still giving us the run around. I talked to one of rhe managers and still nothing. Smh. I don't like Preferred in Grand Haven, MI.
