Only had my 4/4 (first & only Morgan) since March this year but current mileage is 2300. Admittedly I am retired but the reason for buying it was to get out & enjoy it which I am doing. My only worry now is the 6000 mile limit on my insurance! May have to use the MX5 a bit more.......
Try calling your Insurer before u go over the mileage - in my experience most are v helpful - only a nominal extra charge - if any!
