I looked up the trade in prices and selling prices in 3 different "blue "books.
The AMA book says that a 82 will sell for $1265. and a 83 for $1275.
The 2001 Kelly Blue book lists the 82 at $960. on trade in and retail at $1360 The 83
lists at $1020. trade in and $1435. retail.
Theap Jones book for 2002 lists the 82 at $311. trade in and $141.retail, the 82 at $371 trade in and $494. retail. Hap Jones is a west coast company so Prices may be higher farther east.
