S3 cab, what to look for?

[macron]

Going to buy one for the missus, probably the last before hips need an SUV, haven't had an Audi for a while (she had an S1 some time ago), any decent buyers guides you could direct me too?

Looking post 2016 facelift so the longer tail, it will be convertible, and probably auto.

Tips on favoured options appreciated, and mechanical things to look out for and/ or check too.

Accept there are few of these and a stupid time of year to buy, but hey ho!

Only wildcard would be if a silly spec non-S came up, but there are only a handful of 2.0 petrols and they're as much as the S!

Longer tail meaning my view of the silhouette from being the golf back end like one of these (first I found)

To the facelift where the arse grew
