I admire your passion and determination. In addition to a lot of work, restoring that car will take proper tools and work space....long term work space
. I'm sure it can be done, and I won't tell you you shouldn't try. But.......you have to ask yourself; "Do I want a car to drive or do I want a car to just work on for the next few years?"
The fact that it's a Bumblebee is intriguing, but if it's not restored properly it will have no more value than any other improperly restored 914. Your pictures tell as much for what they don't show as what they do. Count on there being way more rust than you can see...it's the Iceberg Effect.
There are some other members in the Lower Mainland, you might want to put out a thread asking for one of them to look at the car with you. You're going to need to hook up with 914 guys in your area anyway; might as well start now. Good luck!
