Welcome newbie Ranger,
Great car and yes you will need to buy tweeds, but only from The Edinburgh Mills shops.
Check for rust........
When you have time, remove the front carpets and check for holes in the floorpan, check also for rust where the rear seatbelt anchors go through the wheel arch and get underneath and check the sills along the full length also the outer sills under the plastic capping, then open the bonnet and check for holes in the inner wheel arches particularly under the wiring loom between the ignition coil and the outer wing. Also the rear cross member just forward of the rear bumper, The brackets rust through where the body mounts on to the chassis. Exhaust brackets and u bolts etc.
What Classic do you have and how well does she run ?
Good luck to you
Fred
