Mercedes-Benz of Manchester review
Where do I begin?
Where do I begin??? These people have been beyond helpful, professional and transparent from minute one. Unlike most dealers you can legit tell these are people. Bought my second car from Kara Duffy and her boss Phil this past week. They are very knowledgeable and navigated their stock as well as the banks to get me in quite possibly the perfect rig? I was originally there for a service with Olivia on my 2018 c300? Kara,Phil,Olivia,Jenny,Dawn?.. all great humans. Which is refreshing these days. End rant.
