trailer

Hi everyone,
I am looking to buy a 6X4 foot trailer to use with my kombi (when it is finished) to carry stuff and what not. Does anyone know where to buy a second hand trailer as I want to paint it the same colour as my kombi and think it would be a waste to strip all that nice paint off a new trailer. I have looked in the trading post and they seem pretty dear for what they are. Are there any dealers who sell second hand trailers?

I am based in Melbourne

Thanks heaps chaps
