Indeed, that's what I was thinking.

+1. My recommendation is to include a large amount extra in the budget just for repairs
when buying older "posh" cars. If you stretch your budget in the initial purchase, you'll be looking at financial issues when something inevitably breaks and costs a fortune to repair.
HOWEVER, that's not to say you shouldn't buy these cars! As you've said, you can
repair them cheaply with aftermarket parts. You just have to bear in mind that unlike your run-of-the-mill Holden Barina, if something breaks that can't be replaced with aftermarket parts, it WILL cost you an arm and a leg.
