local dealer has this car. Seems a reasonable price for the shape it is in. Mark http://www.uniquemankato.com/vehicle/3472110/1987-Buick-Grand-National-Mankato-Minnesota-56001
If it looks good underneath (being a car from the rust belt), and if they were willing to kick a $1000 off for mileage and body condition it would be good buy. Nice unmolested GNs are hard to find.
