Here we see a TR6, made from 1968 to 1976. It was very much an "export" car as only 8,370 of the 94,619 made were sold in the UK. Most of the rest went to the US.
Thing is though, out of those 8,370 we find here that as at the end of Q3 of 2014 3,323 were taxed for road use and a further 1,264 were declared to be off the road but not scrapped. We also see that the numbers are seasonal as cars are put on the road for the summer.
Overall then and ignoring imports some 4,587 out of those 8,370 are still in existence more than forty years on which is quite some figure for a car never intended as a collector's item to be laid down and treasured.
In comparison Triumph made something like 500,000 Acclaims and only a couple of hundred are left.
