I'm looking at a 2010 scab , blue, 6.2l. 125k miles. Interior very nice. Shocks rebuilt 10k ago, full tube headers n tune, otherwise stock. Asking price $18500. Issues: rockers are totally gone(michigan truck), cab corners would need replaced also. Has a crease in bed above broken taillight 6"x3". $1000 fix roughly. Passenger mirror broken also. Would need tires immediately. Undercarriage has rust but nothing major. Only leak is from a plug on passenger side of transmission. Overall well taken care of truck just the issues above. What's it worth? Whats a reasonable offer? Thanks
