Hi Ben, The S type was introduced in 1999 during which year 53,000 were produced, with the 2.5 litre not available for export to the USA. The numbers exported to the USA were roughly 50% of the S Types produced. So with a bit of informed guessing about 26,000 S types went to the USA, and again assuming that those that went to the UK were produced with half of them being 3.0 litre cars there were only 13,000 sold in the UK that year. I have tried to find exact figures but Ford who owned Jaguar at that time were far better at engineering than at administration. The 2.5 litre was quite popular but when the 2.7 litre diesel was introduced in 2004 the demand for the 2.5 litre diminished and was eventually discontinued. Enjoy your car, Ben, Regards, Peter
