First one I spotted was a blue s2 parked up on morningside road at about 12ish
then a silver s2 on liberton road at 1ish
a white s2 exige at gilespie crossroads around 2 or 3
and finally I followed either a black or dark blue s2 from Stockbridge untill it disapeared into the petrol station think it would have been about 5.30
