A car that's been stored in an unheated shed for 21 years without moving? Hard telling what may be froze up or rusted together on it by now. If he put the trans in neutral and let the clutch out all the times he was running the engine over the years, odds are the trans and clutch will be OK. If you can, jack the rear end up and let the clutch out in first gear a few times to see if everything is going to function in there. If you're going to try and drive it, take baby steps....a few feet at a time, testing brakes plenty of times before going onto public roads.
