Yeah it all kinda depends on what the wife buys next. She does a lot of driving with work (500+ miles a week) and is looking at a new car to replace her 1.3 96 Fiesta. If she gets something new and derv then we have that for trips away etc so I can splash the cash on something a little more thirsty as I only do about 250 miles a week.
TBH the S4 is a bit of a pipe dream as I think the running costs would cripple me for servicing etc. The Alfa and the Octavia are the top runners at the moment.
I'd recommend test driving the Alfa first.
Terrible driving position, so uncomfortable...
That may be because I'm larger than the average bear though.
I find them OK, my old man has a GT which is pretty mcuh the same inside.
