Absolutely. I have four Mini variants, all of which are over 30 years
old, and one of which is my daily transport. It's marginally modified -
what Mini isn't? - so why should it not be regarded as historic? My Elf
has also done its share of the daily run, and that _is_ as original bar
the fitment of an alternator. So should the fact that I drive it to work
(last year it was may main vehicle) make it any less historic?

Some of these people just talk b*ll*cks for I living I think.

Anyone seen the latest issue of PC, looks like the FIAI [1] is trying
to define what will be classed as a historic vehicle, it seems to come
down to the vehicle being 30 or more years old, maintained in original
condition (does that mean period extras or how it would have come off
the production line?) and *not* used as the owners main method of
motoring. The point of all this is, whilst we might well think
otherwise the legislators (such as the EU) that this organisation will
have the ear of will make it very important for the future of classic
cars. Whilst I welcome any move to stop people taking a classic car
and 'modernising' it I'm not so sure that these vehicles should be
forced to become all but museum items, there is no reason why a 30
plus year old car can't be used as daily transport and preserved- the
tow are not mutually exclusive!
