Only you can decide. The price is right if you inspect it well.
Does it have original tires?
Check the roof to look for cracks, stains or water puddling.
Does the under carriage have any rust or looks like its been around salt water?
Check all the appliances as they are the most expensive to replace if they don't work.
If it looks like it has been well cared for buy it.
If you still have questions have a dealer take a look at it for a few bucks.
Good luck and let us know what you decided.
