If its as good as you say and has all previous mots and documented history , no rust on the a posts or sills , no rust on the inner rear wings , no rust on the back panel and the rear wheel arches are solid and the doors are in rust free condition with it being such low miles i would guess anywhere from £1750 to £3000 . Its just about finding the right person whos looking for a strada at that time . Stradas with low mileage are very hard to find now . I know i gave up trying ?
