Lots of opinions/suggestions above...
My opinion (for what its worth

)
Mokka at that price point...i looked at one when they first came out, wasnt impressed by either boot or cabin space, too cramped. And an almost lifelong Vauxhall man, i long since conceded they're simply not the cars they used to be. IME, the paintwork is super thin, has been for years now.
Tucson, the older ones perhaps. Our local farmer / potato growers has two (around 2005 iirc). Loves them yet doesnt really do anything other than service them and put fuel in, very reliable for him
Tucson vs Mokka, tbf i'm talking later models, my daughter has one and loves it, my manager had a Tucson, loved it, someone wrote it off and he brought a Mokka, he hates it.
Skoda Yeti or Roomster, they always appeal to me as very versatile cars
At one stage, the Zafira was really quite cheap but they do have a bad rap, yet there's lots of them around, quite versatile but...
Fiat Doblo, if you can get the seated version, its not pretty but its bloomin versatile. SIL has a 2005 one, quite frugal, very cavernous, the 1.9 diesel is strong.
