In germany they start production on cars for their market before ours, the official left hand drive escort cosworths came out before the rhd's,same with xr3's.
you could get w,x,y reg uk spec xr3 and you could get xr3i's on a y reg too or if the car was a left hand drive imported into the uk i saw x reg xr3i's.
and again the same went for rs1600i's,they came out in germany before the uk and i have seen lhd x reg rs1600i's.
