Okay, I’ll be that guy & suggest maybe consider delaying buying a kart & prioritize finishing college instead. The circumstances you’re describing vs the logistics involved in kart ownership don’t mesh, IMO. Personally, there’s no way I could have enjoyed running a kart while I was attending college. There’s enough going on just managing course load work (What’s your major?), then stack on trying to fit the responsibility of maintaining & storing a kart & dealing with any potential security issues if it’s being kept in a public facility environment… I’m just not seeing the fun in that. But that’s me. OTOH, if you have a home garage, then I guess maybe you can swing it.
Personally, I only ever had enough coin + time for tuition + books + gas + basic necessities. Recreation at this level for me was off the table.
