To all you S4 owners out there, I purchased a 2016 A4 avant 2.0tdi S-Line last year as I was starting a new job and thought I would be doing long journeys and needed the economy. A year in, ive done 13,000 miles and tbh I’m averaging 54 to the gallon. I love the size, shape and styling of the s-line avant but want a bit more....well grunt. I’m seriously toying with upgrading to a used S4, most likely a 2017. However I know if I go and test drive one, I know the heart will rule the head and I will whack down the deposit. Before I do I wondered if you own an S4 whether you could share some real life about what it is like as a daily driver. For example all the reviews I have seen shows it’s performance on an open A road, which is great. However I had an M3 that was great on the open road, but was like a bag of spanner’s on stop start traffic in city centres. Any good or bad points will be much appreciated.
