Thanks Peter.
Interestingly, I too bought my Company car when I retired 15 years ago now, and yesterday it passed its annual M.O.T. but with a number of advisories. None serious but all will require continued investment on my part.
My aggregate mileage is now 247,000 over its 17 years since first registration giving an average annual mileage of only 14,500 ,some way behind you.
