Hmmm....
The evidence: it appears to be an E46 GTR (not in factory colours, with a sponsor that uses an "S" as a logo - not Schnitzer.... - number 73). Driving through a left hand bend on a verdant circuit, devoid of armco. Advertising banner shows the word Auto at the end of a line, so probably European (unlikely to be British)
