Retro Fit Traction Control

Hi Guys,

When i bought my 1 i was lucky that as it had been a dealer demo (Archers of Ashby i think) so its loaded with extras that were optional or standard on ST2 or ST3's. My question is tho, can i retro fit the traction control/ESP or is it alot more complicated than just getting a switch I know alot of people like to drive with it switched off, me included - but then i don't have a choice.... but it would be nice to have the option and another toy on the list of goodies the car shouldn't have

Thanks in advance
Dave
