Matthew the manager is the best. My 2nd visit since IGB took over and very disappointed they no longer give 10% veteran or loyalty discount as are other friends I have spoken to. I have spent $800 in last 6 months and it certainly would have helped since according to another GMC dealer I was overcharged by $150 on my work done in November on my van on the wheel bearing labor work. Am researching another dealership that gives discount even though it is not as convenient. FYI we go to IGB for both of our Mercedes since we moved from Maryland so I feel we definitely should get a loyalty discount and we bought another Mercedes 2 years ago from them. I would like to hear from you on this matter. Again, Matthew is the best and very thorough and knowledgeable!!!
