It's not unusual for owners to be completely ignorant of what's 
going on with their cars. And it's often not fair to just accept what a 
mechanic says either, because some of what they say will be 
affected by how they feel when they see you drive in their garage.

My rule of thumb is that every type 3 I buy will get a complete 
overhaul of the brakes and the engine. Often the engine can wait, 
however. Fix it up as best you can right away, then drive it until 
you're pretty sure you KNOW what the problems are. The low 
compression could be rings, valves, valve adjustment, or pulled 
head studs, or just a poor diagnosis, or ....
