Nothing struck me as being odd. The previous owners have taken the time to keep her looking good, clean, woodwork looks good. There were a few oddities, the small apartment sized refrigerator and the seawater strainer for the engine lying on its side.
Unless the boat has an enormous battery bank, that refrigerator will only run when connected to shore power. I've never seen a seawater strainer sitting on its side.
I suspect the cabin sole has been replaced. There is a shot showing the salon and the nicely varnished cabin sole with plastic access ports. That seems an unusual arrangement. Also in the same scene there is an mis match on the cabin soles. The scene is 40 seconds into the video.
Without seeing the boat, it is hard to say what the actual value is. Well, the actual value what someone is will to pay for it. It is interesting that all, but one, of the Tartan 33s on Yachtworld have recently lowered their price. That suggests the market is soft these older boats and the owners and brokers may have unrealistic expectations.
Things I saw that might be holding down the price was the jib, a new one is probably in the $2-3K range, the gas engine, the refrigerator, and the age of the boat. The other boat I took a quick look at seemed to be better equipped for cruising and had solar panels. One has to wonder why the cabin sole was replaced. The other T33 I looked at did not have the plastic inspection ports in the sole. Older boats are also harder to insure, especially in Florida.
Depending on what you intend to do with the boat, it may be a good boat for you, or maybe not. If you decide this might be the boat for you, then be certain to have it surveyed.
Good Luck!
