Hmm, not sure i’d agree that beyond big unaffordable mercs and the xc40, you’re only option for a big car is a ‘budget’ korean.
There are plenty of options over saloons, mpv’s and suv’s.
Nor would I concur that the decent sized and spec’d koreans are actually budget cars. A well spec’d auto Tucson comes in at over £30k, hardly ‘budget’, well not to me at least.
