To be honest mileage is getting abit irrelevent on these cars now, so many have been rebuild, refurbished that even though it may say 100k for example on the clocks there just as good as they were brand new.
Mines got 22k clocks on it (new ones bought few years ago) but car has originally done about 110k. Almost everything has been changed and body sorted out so almost like new now, mileage doesn't bother me one bit anymore.
But good luck anyway mate in finding what your after, in the end you'll be happy with it
