I’d be a bit kinder than Ziggy, maybe £1000 to the right person.
From personal experience of low mileage mk2 puntos, they tend to have weird problems, like separating clutch plates due to surface rust. Rubber hoses and seals dry up and leak. And despite the low mileage, unless it’s been kept in a warm dry climate controlled garage, it can still rust, maybe not at bad as one that’s been on the road but rust is enough to scrap much newer cars than 2000.
It would be nice to see it, if it is in tip top condition without rust, definitely an enthusiasts car. But not worth much if it’s a standard model.
