Welcome Frank, and thanks for joining.
You will hopefully get other views to help you make your decision.
I must admit that I am not basing my comments on personal experience, but on that gained by an elderly friend, who was totally disappointed with the ride comfort of a newish S Line - chosen by his children - due to its ‘look’.
I think, but I’m not certain, that Audi seem to link the attractive specifications and ‘toys’ with the S Line, so if you want these attractive features then you have to ‘put up with’ the harsher ride quality. It’s worth examining these cars in terms of possible low profile, possibly XL load rated tyres often associated with larger wheels, which further aggravate the ride quality.
Technik? Sorry Frank - no knowledge.
Does this all boil down to style vs ride quality -as you think?
I feel it likely does, so the decision has to be made to go with which of these two is most important to you.
Please remember that this is a one-person opinion, but possibly includes a couple of pointers to guide your options while you await other advice.
Good luck and kind regards,
Gareth.
