Sunday afternoon about 3ish, just past Tescos on the A421 in Buckingham. MINT looking white F reg with supercharger rear lights. Certainly sounded like a supercharger but didn't get a chance to see any more of the car!
IMOC-UK - the only club to win 'Best Club Stand' at JAE more than once, and twice in a row!
Hmmm. Possibly me coming back from the Retro Show at Santa Pod!? Certainly the right time/location. My car isn't supercharged but it does have the import light clusters.
