I have a SEAT Ibiza 1.4 petrol SE Copa five-door in silver on 61 plate with 8000 miles on the clock with all the buttons, auto lights, wipers, climate, cruise, trip computer, electric mirrors, aux in, auto dimming mirror etc

Could I reasonably expect to walk into a dealership, trade it for a second-hand Mii, and not have to fork out extra ££ in the trade?

My journeys consist of:

95% of <1 mile
4% of <50 miles
1% of <300 miles
