I'm interested in buying this 2004 SX Venom with 6,400 miles on it. It has a new track that is studded down the middle. Electric start and reverse. No tears in the seat. The bad, it has a couple pinholes in the silencer, the other pipe is out of a wrecked sled and has a dent in it. The exhaust was spray can painted to hide the rust and looks like crap. I also noticed the carb boots are wrapped with electrical tape. The left ski is damaged on the outer edge pretty ugly but not sure if it needs to be replaced. Now the story, he bought it less than a year ago for $1800 and he will sell it to me for no less than $1200. What should I worry about here???
