As I'm sure you'll appreciate, giving you a value for a specific car isn't possible - we have no idea of the history or the condition - but we can give you a rough guide. Although they're few and far between, Nissan Sunnys are still at the fringe of the modern classic motoring scene. So it's not uncommon to find exceptional examples in the back of local newspapers for under £500. However, there is one currently for sale online with 46,000 on the clock and an asking price just shy of £1700. We think this is a touch ambitious, and we'll never know what the car sells for, but somewhere in between should be about right for your car. Will it appreciate? If you keep it in a good condition, it could do - albeit it at a slower pace than some of its contemporaries.
