A little high priced but I imagine there is some wiggle room. Gulf Stream was a good name and their woodwork was typically top notch.
Something like this would encourage me having all of the running stock gone over with a fine toothed comb. Oil analysis on the engine oil and tranny would be money well spent absent any maintenance records.
Leak checks all around, Water tanks inspected for FGS (fuzzy green stuff) and I'm also looking in every nook and cranny for signs of stowaways - the rig has had to have been sitting in one place for a very long time.
Still a buyable option - after a detailed 2 pairs of eyes inspection.
