I've spotted a fellow TDIclub forum member twice on the highway in the southern NH and eastern MA area with NH vanity plate NOXIOUS, on a JSW TDI of course. I've spotted the car twice, the last time was at night on I-95 southbound in Portsmouth NH and behind my X5 35d with NH vanity BMW-X5D. I have metal TDIclub YES, IT'S A DIESEL license plate frames on my cars.
I owned a V10 Touareg for about 6 months and had the NH vanity plate TQMNSTR along with a Greta sticker with her leering directly at the V10 callout and declaring, "How dare you!" Sold the T'reg, new owner kept the sticker in place and now have the plates registered to a B4 that is long gone on the chance they can go back on another V10 in the future.
