Went to the dealer to see about ordering a F450. He was looking to see what was out there and found a 08 job 1 truck on a lot in another state with all the options I'm looking for. He said 08's have a $8K rebate, stickers at $53,160 and he could sell it to me for around $44k. Just wondering if I need to worry about anything with that truck? Went in planning to order one, then he finds this one....what to do?
