Back to the CityRover, the mark 1 sold poorly since it was not much more than a badged Indica and not up to UK standards. The mark 2 is a big improvement and would have sold well except that MG-Rover went into administration just as the first shipload was arriving. However the remaining ones intended for MG-Rover are currently selling very well and Tata have announced that they will set up UK Tata dealers to continue sales.
"How many CityRovers/Tata's did they sell in england."
There are no figures for just England and I don't know where to find UK figures but the Europe (mainly UK) sales were:
2003-487, 2004-6150, 2005-1636
Not sure if 2005 includes ones not sold by MGR - ie the ones stuck on ships at administration and ones built since.
