What do you think its worth?

87 GL Syncro "Weekender" w/ 190K and leaking heads.  Diff. lock, Alloys,
A/C, dual heat, new exhaust and rear drums.  Body has minor surficial
seam rust and a few scratches but no dents or major dings.  I need to
sell soon and am asking @ $4000.  Everything works in this van, is this
a reasonable price?

Any ideas?  Dave.
