Varies.
The first couple of years I didn't do more than 1000 or so per year - but I was still battling with front end shimmy.
Once that was eventually sorted, I've been running 2,500 - 3,000 (except 2011 where a single week's trip was 2182 miles). 2 years ago I guess it was very close to the insurance limit of 5k - certainly well over 4k. Last year back down to 3k. Will have a week in Scotland this year (all being well), so mileage will be up again.
Cheers,
