This past weekend I took the Peerless to a British car show here in Los Angeles. Dean was there but had his Lotus Europa.... In the course of the time I was there, many people came by and asked about the car, or commented on never having seen one before etc. There were undoubtedly more people, because as I was away from the car more than with it.
So here is a suggestion - a QR code. Not everyone may know what a QR code is, but they are the square, blocky barcode images you might see around. Basically, you point a smartphone with a QR reader app at the code, and you get linked to a website or some other source of information
This QR code below points to www.peerless-gt.co.uk I've printed it out, put it in the car window and it works perfectly.
If you like the idea, just print it too. And if you want one for any other purpose, they're very easy to create
