I've only seen 2 in my area, South Buckinghamshire over the last 2 years. Clocked a white one in 2009 but didn't know what it was at the time. Turned out to be a friends dad's car and was eventually sold to Nick who has recently posted on here (coming back to ISF). The ISF does do a great job at getting from A to B @Jgtcracer, very quickly, if required. ☺
