What to look out for in a used Car Transporter

[Jimbo NW]

I'm (hopefully) to be getting my B+E license tomorrow as I fall outside the grandfather rights period on the license.

I've been looking at both Brian James and Woodford trailers both new and used and have given myself a tentative budget of £2.5k which should be perfect for what I need.

Being an IT sales person, I'm a bit of an idiot in terms of what to look for as issues on a used unit, other than surface rust, dodgy handbreak so I wanted to reach out to the wealth of knowledge that is pistonheads to see if anyone could point me in the right direction as to what to look out for?
eBay is a mindfield and confusing me more than helping!
