2010 vs 2014? lol
Toyota, Honda and Audi are all known for quality and despite the Audi B8 having quite a lot of issues (engine and suspension) I believe they were mostly covered by warranties by 2012, last production year of that generation. You would generally get the same level of luxury and performance at a cheaper price with the TSX, not to mention better fuel economy. The IS250 would only be a better choice if you prefer a more sporty feel, plan to take it to mosport / cayuga (because oversteer is more fun than understeer) and/or want a more recognized premium brand than Acura.
Also, since you considered an A4, there are decent Mercedes-Benz C300 and E90 BMW 328i to be found within your budget.
Audi is known for quality???? Known by who? Do you have a quality metric that shows this?
I'd put Honda down for reliable. My old 91 si was at 400+ and my friend who bought it off me got to 800 before it finally died. Another friends 98 civic made it to 590 before death. The body falling off is an issue however.
It's easier to do anything on an engine than to restore a rotten body. While many might not care how the car looks, in case of an accident I rather be in an old audi with all it's quirks than an old civic that'll bend like cardboard.
To me nothing is of greater luxury than stepping out your front door into your car & turning that ignition and driving away.
After owning German cars you'll come to understand what I mean
I've found people that take short cuts with maintenance on a German car, get bit in the ***. Whereas a Honda will run on water if it needs to.
Couple of Audi's and a Beemer, never been stranded in over a decade. But these cars are like high end gf's. Gotta keep them happy otherwise...
