My glass isn't exactly half empty but lets say slightly less full....at least unless you prove to yourself all is OK.
I considered an ex-hire myself.
What you might find is that some of the less hardy hab area bits have already taken a bashing rather than how they will stand up in future and perhaps thats what you meant?
My thoughts are that many people have hired for the first time and it's easy to do things like....
A) get the seats in the wrong position when attempting to swivel them marking the B pillar & door trims
B) stand on the captain chair arms to get into the pop top and over strain/break them
C) Break the kitchen cupboard door handles
D) Not take care of/support the awning properly when winding it in and out
E) Mishandle the blinds
All of the above can be done by anyone (including you if you bought new) so it's going to come down to confidence, knowledge and cost.
Likewise for the outside, every hire vehicle I have had gives you an allowance for small dents and scratches and most of them have had that when I first picked them up so its not uncommon.
It really is all about what can be fixed properly and how that is reflected in the cost.
Some will be worth buying for sure. Good Luck
