Juel, check out Edmunds for new and used prices, invoices, etc. Kelley Blue Book has much less information, but worth comparing. I got about 55% of 2002 MSRP for a V8 SR5 with average options for then and scratched paint from using it like a pick up (trees branches while cutting up dead trees are not good for paint). 65% for a 2005 might not be so good. $7,000 of a new one must be a Limited—more room to bargain on those. In Sept., Toyota had $2,500 rebate on SR5's. They add on about $1,600 to invoice for adv. fee, holdbacks, manufacturer to dealer cash; there's a little room for bargaining there, but the dealer won't give up much of that. Considering selling your 2005 privately—better money. I only traded because I got a got price both ways.
Be strong Juel and buy a new one, then post the pix.
