Are there 'vintage years' for Seacraft hulls?

[dmaci]

The following 18' seacraft, a refurbished 1980s hull (says 1999 but that is the date that it was redone), is being advertised for $14K:

Motor supposed has low hours and the boat certainly looks clean. I understand that different companies have manufactured Sea Crafts over the years, but haven't been able to find out whether there are 'vintage' years or does it make no difference. I like the 18' but what should I look out for?
