There's a thread on a UK hot rodding site that shows old pics of US/Canadian cars on the street in the UK during the 60's.
One of the guys posted up this pic that was taken in April 67 , thought you guys might find it interesting...note it's still on CA plates UCX 973 , is it traceable from that ?.
Looks to be a Mk1 Lotus Cortina in the background too.
Complete thread is here should you be interested ...
