I live in Baltimore, the Ham-Roll (the strip between Hampden and Roland Park right by JHU)
There are at least four other MK7 Rs within a mile, and I've been seeing a grey one over by my son's school in the morning, so that may be five. It's kind of nuts, but the R is very popular with hipsters with a spot of scratch.
There are at least three MK6s I see in the neighborhood as well, plus another dad at my younger son's daycare who drives a MK6.
