I agree, the S2 with a manual box is a car you can really get into driving and matching revs up and down etc. First is a pain with a bit of rev hang and the clutch angle. Not much space to relax your leg/foot. The ZF 6sp auto on the Coupe does match it very well and using the manual tip changes at anything up to 90% go is lovely if you do want to row it along.
It is surprising how different the character of two cars built on the same chassis is. Mk1 even more so I guess.
