I'm pretty sure the design is the same regardless of year ... I know the later boot carpets came with a Z logo and previous ones didn't ...
I got mine from eBay not long after purchasing my Zed ... think I paid around £35 inc delivery ... they weren't brand new but had hardly any signs of use on them ...
I've just had a quick look and there are some Brand New Genuine Mats for £59.99 delivered ...

Personally I would recommend buying Genuine ones ...but I'm sure there are other members who've purchased tailored ones which are just as good ...
Good luck!
