Hi Graham, My neighbour has a Mazda 6 and when coming back from his house in France it always used to go into limp mode due to the DPF. He had it removed! The s type diesel more or less took over the market that the 2.5 litre petrol had, and became very popular, and personally, I do like it as it is a superb engine. But there are still quite a few late models around , and in the USA both the 3 litre and the 4.2 litre R are very popular cars. There are quite a few late models around if you do a search online. At the same time the XK8 is a very nice car, and if I was as young as you I might think about one myself. Regards, Peter.
