I'm in the market for a vintage Airstream in excellent/restored/remodeled condition so I started a spreadsheet to get an idea of list prices. I know there are still more sources to add, so it will probably grow.
Disclaimer: These are LIST PRICES and the condition is self-reported by the seller. Also, the features of restored and remodeled trailers vary widely, as do the prices, so I don't know how helpful this is, but I just wanted to get an idea of the range and a ballpark average. I thought I saw a list of actual purchase prices of vintage AS somewhere, but lost the link ... it'd be interesting to compare the two.
