Thank you for your input!I've been to both Porsche South Shore in Long Island and Manhattan Motorcars. While Manhattan Motorcars does have multiple brands, they definitely are a full fledged Porsche dealer, you'll deal with a Porsche SA and everything like the other dealers. The other brand they carry are low volume (Bugatti, Lamborghini) type cars, when I was there I only saw Porsches in the service bay. It's more like a Porsche dealership with some mechanics specializing in those other brands.
Ultimately they're all just VW ?
