FunkyDunc is right, except that a Mondeo is the size of a truck which can be annoying. But they’re cheaper for equivalent cars.
I had a ’52 plate, mk 1.5 Focus with 120000 miles when I sold it, and the worst engine, the 1.8TDDI. Brilliant wee car, but it was pretty clapped out, quite a bit of rust and it didn’t generally give the impression it was ever going to get through an MOT without a bill again, and it had clutch, turbo and dmf hanging over it. So I’d want to buy newer and lower miles if I could. The 2.0 TDCI in the Focus is a match made in heaven though in some ways newer Foci are worse, they use the space less well and the ergonomics can be weird. More modern but generally feels less well nailed together.
( I got my ’55 mondeo on 90000, that’s probably still higher than is ideal but I got 20000 odd miles out of it with barely a rattle. Then an expensive year with the turbo and injectors but it’s still sound. I think realistically to get a 30000 mile younger car I’d have spent about a grand more so it’d still be pretty equal on cost)
Octavia, I dunno, maybe a better car. I get irate about the boot on the estate though.
