Looking for guidance

[csvencer]

I recently found a '72 V20 Steplift for sale, the guy is just looking to get rid off it, I am sure I can drive off for less then $750 (if the trailer is roadworthy). The boat looks like it has some serious cleaning to be done, lots of mold and crap growing on it from sitting under some trees. The motor is seized and the trailer looks OK from the pics and he says there are no soft spots in the floor. Besides a solid transom what else should I be looking for? If it was any real significant amount of money I would get a survey, but I don't see the point of surveying a boat this cheap. What is the potential for something like this?

Thanks for any help/guidance, I have been searching a lot of old threads and found some good info on here.
