My first tractor was a new 2005 Kubota B7510HST with the LA302 FEL. Cost was $12,600 plus sales tax.
I traded it in Mar 2008 with about 200 hours showing for a new Mahindra 5525 and got $7800.
Today the trade in value is $6-6.8K and the retail is $8.2-9.1K. If you're buying from a dealer, then $9.5K is in the ball park. If it's a private deal, then $9.5K is high--should be more like $8.5K
