Nah I think that it was definately a 182, well it has anthrite cup alloys, standard silver seat belts and standard 182 exhaust,lol.
Well I just go straight to work (Linde HTD in Pentrebach) and back home in Blackwood apart from Tuesday nights were I go to Merthyr College other than that I dont spend much time around Merthyr area.
Never seen your 172 about either but I did see a lowered silver 172 in college car park last Tuesday was pretty loud when it pulled of aswell, looked good.
