CSL tyres - what they worth?

[Das Chin]

am thinking about going for some cups all round.

current set up is a bit 'mixed' so not sure of worth/value. but they are proper CSL sizes and top brand road tyres (Michelin all round)

fronts:
235/35/19 ZR Michelin Pilot Sport 2
1 has 5.5mm
1 has 6.5/7mm
no punctures or repairs
would like to sell as a pair.
£200?

a pic here to see the fronts as car was in the air:

rears:
265/30/19 ZR Michelin Super Sports
both have 5.5mm across the tyres
no punctures or repairs
would like to sell as a pair.
£275?

if you are interested in them then drop me a PM.

any ideas on pricing would be great. will have a look on PistonHeads.

I want to avoid Cutters if I can for obvious reasons!!

thanks, NW
