Add new question to the seller

I am very interested in the boat. If possible, I would like to come take a look at it. I also have a few questions:
Aside from the carb and the old gas, any real issues(non cosmetic)?
Is the trailer in good shape?
How do you like the tri hull? I have read some mixed reviews about tri hull, some say its too rough of a ride but very stable when sitting(Not a deal breaker for me, just curious of your thoughts).
Let me know if there is a good day that I could come take a look at it. Is $500 firm?
