I've had my '94 Sundancer 330 going on 5 seasons now. The boat was very well maintained before I even purchased it, so it was in very good condition. Outside of typical maintenance type things you have to do, I've been very pleased with the boat. She's very seaworthy. I had to take her through 7-10' seas once and she did well.
The radar and Loran/Fishfinder are still OEM and functioning. The biggest thing is 'how well was it maintained'. If the boat was properly cared for, you should get many years of boating fun from it. When people see it for the first time, they can't believe it's a '94. That's the type of response you want.
With boats this vintage, you will have to consider some improvements/upgrades since things just wear out. However, the engines/V drives have been performing very well. Although I had to replace an engine a few years ago, feedback from mechanics indicated it could have been a manufacturing defect. My engines have about the same # of hours as you do. Also, a good surveyor can be invaluable. Any possible issues can be identified and resolved by the owner BEFORE you purchase it.
Hope this helps.
