10 yrs. of storage.

[Diggedirt]

I am a new member who has owned a 72 Mach 1 for 11 years, 10 of which the stang has regrettably spent in outdoor storage. I finally have a garage in which to store/work on the mustang. What I need to do is determine if restoration is a justifiable action(beyond sentimental reasons)or if selling/parting out(ouch!)is a better plan. The car ran when it was parked and is complete. I would like to know how to go about a complete rust inspection to determine the damage already done and ballpark estimate the cost to repair. I would also like to know what I need to do to the engine,etc. because of the long storage term. If anyone has info or links for these subjects I would greatly appreciate any help.
