Genuine hpi clear shell

[Karl 04lsb]

Hi

I’ve got the opportunity to buy a genuine csl shell which is bare just has the glass and csl roof mainly

It’s been in storage for many many years and was a track car build that never got off the ground

I’m interested to maybe do my own track build with

But I’ve been asked to make a offer if interested but don’t know where to start at all

Where would you guys price it at???

Shell is hpi clear and comes with logbook etc

I don’t want to offend the seller with a lowball offer but don’t know where to price it as I’ve never seen another for sale

Any help would be greatly appreciated
