I have the Classic Jersey, it's really really nice (also part purchased with a Christmas present voucher), adds nothing in terms of technicalness and I know they are stupidly expensive but it adds a feel good factor to my rides that is hard to quantify. I actually want to go out on my bike more so I can wear it!
In the future I may get a pair of classic bib shorts to complete the outfit but that's a fair bit of saving up away!
