Depends what you call a banger
My friend has an - admittedly diesel - Mk1 Leon of 55 vintage that's a delight to behold... if not hear. Though my 54 Octavia vRS is slipping into banger territory because I let it go that way. So it's a grey area hehe
Some kind of Ford perhaps? I like some of the models of the 09 region Mondeo (I never look at the other Fords from a "hmm, maybe" perspective), such as the... what's it called, Titanium X Sport or something? 2.0 petrol? Dunno.
If you're going smaller then maybe just older versions of what you're looking at. But with nicer engines.
What does your lady friend drive?
