Can you send me some resources that I can use as a guide so I will know what to consider when purchasing a vehicle?
Sure! Read the DMV brochures, Let the Buyer Be Aware, and Q&A About Your Title Certificate
By the way,  for my snowmobile registration,  why can't I enter my complete address on the NY registration for my snowmobile from Alabama?
The snowmobile registration system only allows for 20 characters for the street address and 14 characters for the city.
