Our Market Watch section is an online searchable database and it is smart phone friendly. It was set up as a database for vehicle price data; however we have added other collectibles as well. For example, under “Make” you can search for Paul McCartney for price data related to Paul McCartney collectibles. You can also use the database to see what celebrity ownership of a vehicle does to the value. For example, under “Model” search for Trans Am, click here to view the results. You can also search the Market Watch for famous/well know collections that have sold, for example, here is the data for the Bruce Weiner Microcar Auction. And here is the data for the Lee Roy Hartung collection that sold years ago. We have also included price data from TV shows such as Jay Lenos Garage, American Pickers, and others, simply search under “Make” for Jay Lenos Garage and click on search.  The database allows you to compare asking price, book value, actual sale price, etc.  You can also view offers versus sale price.  Click here to view offers versus sale price.  The database includes aircraft, cars, motorcycles, bicycles, collectibles, avionics, engines, car parts, aircraft parts, and more.
