which to buy, a 2006 or 2008 LSV?

[Wax]

I am about to list my 07 LSV for $28. 190hrs. Gravity3, perfect pass, dual battery, stainless rub rail, docking lights. interior leds, pop up cleats 4 amps, sub and custom Bimini.... But needs new trailer as mine is starting to rust. Sorry not trying to hijack or selfless promote

My neighbor has a double axle Supra trailer for sale...

Why would he need a new trailer if it's just rust? Couldn't you just sand and paint it?
