Cabrio rear window PVC - options?

[emmaitch]

Hi there. Need to replace zip-in window, wondered if there's only one standard PVC - ie 1mm thick/40thou - or is there a 'premium' type that will withstand scratches/discolouring for longer? And companies in London/south east who'd do the work?

Don't know about the diferent quality, but i bought mine off ebay and fitted it myself

Think i paid about £95 there a bit cheaper now i think
