Hi all, I've been through many builds in the past from JDM to BMWs etc. and am considering a C4S near the top of my current list of cars I'm considering. Being in a C2 in the past, I miss the feel and the comfort of 90's era ergonomics (newer interiors/seats are havoc on my back, not to mention the head-forward headrests). Now, aside from the usual punch list, is there anything else I need to scrutinize, say the front diff, extra electronics, etc? Currently finalizing my purchase decision so I'd like to make the most informed decision and figured I'd ask the guys who know. Thanks!
