Looking at upgrading my harnesses and need to sell my Sabelt 4 Point ones x 2, not sure what they are worth any ideas?

How old are they?

Not sure, they were in the car when I bought it just over 12 months ago which was built by MK cars in 2009......

I bought a new pair for £50 last year, but thought they were a bit of a bargain.
