I live in Nailsea & have got a White 100HP. it wasn't me who flashed you but.....the other week i was in Tesco & got back to the car only to find another White 100HP + owners parked next to mine. turns out they only live around the corner.
so chances are it was them that flashed you unless Nailsea's been taken over by a White Panda Invasion
how long have you had yours? It was the sight of a Black one like yours flying through Wraxall one day last year that made me think "I'm getting one of those" !!
unfortunately a bit of an expensive MOT this year ( buckled wheel - my fault & rear shocks ) but still the only car i've had that i actually look forward to getting in & turning the key.
Ah ah! I seem to spot absolutely loads of Panda 100HPs in Nailsea! I work there but live in Portishead
I've had mine approx 1.5 years
Mine is pretty easy to spot now - It has a permanent roof-rack and compressed gas sticker on the boot lid. (+ the fiatforum.co.uk sticker on the rear window)
