Not sure you're likely to get an accurate view of the average annual mileage covered by Morgans by this poll, there's too much self-selection going on, firstly to participate on TM, and secondly to be willing to tell others of the mileage covered. These factors will skew the results to favour enthusiastic Morgan owners who use their cars a lot.
According to people I've spoken to on the servicing side of things, by far the majority of Morgan owners do vanishingly small annual mileages, anything much over 1,000 miles/year is unusual. The guy who MOT's my Morgan for example regularly tests two others, neither of which apparently does more than a couple of hundred miles a year.
You will of course get a representative view of the mileages covered by TM members who wish to participate in the poll, which irprobably the more interesting statistic anyway, although personally I'd like to see the data split by working/retired people...
