Is it worth it?

Looks like it is on the dry side of the mountains. "Rough" to you would be "pristine" to most guys in the east. Check for rust - all around rear wheels, lower doors, floors, cowl. The later is very hard to repair. That set of wheels is worth at least $250. A car show claimed the rear glass is $2000, but don't believe that. $2500 wouldn't be an unfair price, but try to knock him down to $2000 if it doesn't have working front disk brakes (appears to be drums from photo). I expect these early Barracudas will become much more valuable over time. They are a unique look and modern car designs are moving towards them, so will be "retro cool".
