I came across this website recently which should shed some light on how many of our beloved M3's are left.
It seems to get the numbers from both taxed and sorn cars.
I don't know if I have read this correctly but it looks like there aren't many left in the UK.
The section on the right lists the 2010 data, and it appears that there were only 136 cars either taxed or sorn in this year.
Have I red this right? have a look and see wht you think.
If this is right, they should be on thi endangered list.
