The 1989 is a good year I think.
Wayne and others have inputed that these models might increase in value more than some of the 964 models.
I was looking at Bruce Anderson's market update of these years and this is his most recent price range.
for the 1989 Cab.
Low is 19012.
Good is 21616.
Excellent is 28938.
I would think if the PPI comes back with only minor probs. you could get it in the 22k range.
If the car has been garaged a bonus in your area if they salt roads.
In cal we seem to have the best pick, so if not too many pop up in your area it might be hard to get the seller to lower the price.
Post the results of the PPI I am sure others will comment soon.
