The MG Rover build data we have goes from 1999 up to the collapse of MG Rover in 2005. It covers some 250,000 vehicles and you can get interesting information regarding your vehicle from the data, such as when it rolled off the line, what market it was built for (was it re-imported before you bought it?)
