I took an A5 for a quick spin at the dealership yesterday. Only drove on city streets at low speed since it was close to rush hour and the freeway was congested. The lines of the body are really nice like the S5 and the interior is smooth too. First thing I noticed (as an S4 driver) is the quietness of the car. I mean it is pretty fast an when you punch it has a bit of a growl, but nothing like the good ol V8. It might sound pretty good though with an aftermarket exhaust. I guess overall I wasn't that impressed with the car, especially at $50k. I'd most definitely spend the additional $8k for the S5 even if the wait time is like a year or so. I just was curious if the A5 would be anything like the S5 and other than appearance, it totally isn't.
Maybe I'll have to give it another more extended drive again later. But for the moment there's no chance I'd trade my S4 for one.
