They ride terribly and are highly prone to failure...
Fold is lengthy.
Old aluminium.
Get a Brompton
You could look out for a Riese & Muller Birdy - the old ones are pretty decent and they’re German so you might find some local bargains. Again aluminium, check for cracks on head tube, forks and rear triangle.
Not willing to spend €€€ for a Bromton though. Budget is like 100 max.
For me a folding bike will just be a bad weather alternative / have a bit of fun project for the shit weather period.
