Hi Jim,
I too have a 90 with a 200tdi it's a 1989 model , like yourself I have never managed to any events yet but really keen to get to one, my problem is that I stay way down in darkest south Ayrshire and most events are north of Glasgow , probably a 6 hr return journey, however I am starting to trust the reliability of my Landy after a few issues early on .
Best idea for me would be to travel up on the Saturday and either stay with my daughter in East Kilbride or treat my good lady to an overnight in a nice hotel .
All the best with your Landrover , this is a fantastic site everyone so helpful and friendly,
Cheers
Donald
