It is all about the rust.
Rust free, decent interior, decent tires, non-runner 2,000 to 4,000. depending on receipts provided for repairs completed.
Rust bucket $500 to $1,000
You can score a decent running... rust free... bullnose in Arizona for about $5000 to $8,000. Couple grand to ship.... and you have a solid base to build on. If you drop 3,000 on a rust bucket plan on doing another 3,000 in rust repair to keep it from turning to dust. At 6,000 you just fixed the body rust and more than likely every bolt is rusted. Every part you pull will be a nightmare. The Arizona Bronco will save you blood, sweat, and tears in the long run.
Unless you are an experienced restoration expert and plan on doing a frame off... but then we would be asking you.
If you just plan to trail drive the hell out of it until it falls apart... then go for it. Parts are cheap and readily available. Maybe use it for a learning experience and don't sink too much into her... while you save for a rust free restoration queen.
The 1986 is a bullnose and non-EFI. I actually think the bullnose are the best and the 1986 is the best year for bullnose.
The 1987 is the first year of EFI and a brick nose... and it has the issues of a first production run.
