If it's in very good condition, no rust, everything working, around $3000.
If it's showing some wear and tear but runs well and is in good shape, around $2000.
If it is in good shape but running poorly or needs repairs, $1500-$2000.
Rust spots like the kind you get in the north (wheel wells, rear storage bin area, door sills) are cancer which needs to be disclosed to know the true value.
A rundown on its operating condition, engine, chassis, brakes and good pics of the engine bay, exterior paint, under carriage and interior would help pin it down.
Does it looks like this?
I bought the Tan One in 2001 from my brother in law for $2,200, pretty much stock, 107,000 miles. The pictures are after I did some cleaning.
