Hi Ian, thanks for your help on this!
Well according to the VIN formula mine is a Cowley build! For no good reason I have always assumed mine was a Longbridge build, donat as why I thought that !
Yes, the sills are colour coded right through, I ordered the Raven black when buying it new,and although it may be a Cowley buil, its generally very well put together and had no problems at all (yet) Reg 04-2000
apart from one period of poor acceleration top speed, etc. which no amount of dealer updates and tinkering about with could cure...I cured it myself in a lateral thinking moment...took up the slack in the throttle cable.Job done !
