storage

i live in orange county and store my boat at bake rv storage and its outside. there is a tige 21v riders edition that is just mest up and is never taken out and is never stored with a cover. The interior is dirty as hell. I was wondering if i should try to buy it and fix it up. Has anyone ever bought a boat like this or would know how hard it would be to fix it. It also has a lite bar with speakers on teh tower and it looks alright from the outside and it could look beter if it was cleaned.
