uuuhh did i do something stupid

i sold my 1973 buick riviera with 85k origanal miles, and im the 2nd owner for 3k, ive been trying to sell it for a year. what do you think? :confused:

Sellers remorse??
Last year for the classic boat tail Riv. I would buy one. 3k is about right for a decent one, but if yours was rough, you got good money for it.
It's worth more with the GS package, and a lot more with the Stage 1 option (my records show it was still avail. in '73. )
However, anyone who really wants a boat tail would buy a '71 or 72, and would pay more for it, so 3 k for a '73 sounds like a fair deal for everyone.
