£6k second car

[lafranr]

Run a 2016 cooper clubman s. Went down to one car from two. Find ourselves caught out on occasions so thinking of getting a second car. Purely low mileage so could just go simple city car for a few grand however I do like character in my cars so get drawn to cars we’ve always liked.
So budget Upto £6k but would prefer lower. Could go fiat 500, Aygo, or maybe Audi TT, abarth 500. Thoughts and suggestions ?
