Yeah i would report him on ebay.
Also , to be honest i don't think you have done too badly though.
I have been sold a lot worse , hence i no longer use ebay.
Boxxer bushings are £90.00 so try and get some 151 to overhaul.
I remember there were new lobo shocks on ebay for £40.00
Also i would put some hope m4's on there as aposed to the mono 6 ti.
Just so happens i have a lovely set with braided hoses and aztec rotors if you want to swap.
There are 2 front calipers post and I.S loads of spares too.
The main concern i would look at is the pivot , it will be a paint to get out and a even bigger paint to source one , so you may need to go to an engineer.
Or get a set of 2001 junior t with the m arch , or a nice set of RST mozo XXL would look sweet.
I would keep the grey rims on there.
I love these bikes and have always wanted one , also dent wise , try having it brazed.
