I am looking to pickup an older rig to fix up and repower. I honestly like working on my current boat as much or more than actually using it

(this is true of most things in my life)
Anyways, I have been searching for some time and found this ad:

I love the lines and it is the perfect size and configuration for the project I have in mind. So, are there any general comments about this vintage Pro-Line? Short of the normal things to be aware of in a 20 year old boat, is there anything special to be aware of on older Pro-Lines?
Muchos Gracias!!
