Very nice car with an amazingly clean engine compartment. Makes you believe that the claimed 31,000 miles is true. Price is actually quite reasonable, too, as this is the kind of car that some sellers would stick on ebay with a $15,000 reserve. At $6,500, it ought to sell quickly.
It might be a fun driver except that I think the 69-70 Buicks were rather unique in their brakes and suspensions which can make finding normal wear parts a bear. If I am mistaken, I hope someone will correct me, this wagon isn't too terrible far from me.
