There are ways to do a quality restoration at a reasonable price. I did my 88 series III over 5 years (not on purpose of course). By taking your time you have the ability to aquire parts as they become available from other owners at reasonable prices.
It is all about who you know and the ability to pick up parts cheap. I had brought most of my parts back with me every time I went to the U.K. and that is a huge savings. I did a complete restoration on a new galvy frame and galvy everything else that rots, engine, and everything except for paint for under $10,000 and that includes the purchase price of the vehicle, which I thought was good.
Patches are for Pirates and pants, not a bulkhead and chassis!
