Viper = shit ...if you know anything about them and their shitty v10 motors. The fact that you put them in the same line up as a z06 or zr1 super car means you're just a magazine flipping enthusiast.
All the cars you're comparing are upper class sports cars and this thread is about an entry level ATS.
...if you don't know the difference between German vs American engineering then you've never spent time in either type of vehicle. Go drive in a 911 for a while or a base German sedan and compare the fit, finish and feel to an american car and it's no contest.
BTW, entry level ATS is beating the 3 series in most comparos, worry about audi first..... Just wait until the next lexus IS platform and Infiniti G...... New gs is already better than F10 5 series aside power of the 550 and M5
Want to talk about build quality currently for germans its audi 1st, bmw maybe 2nd and MB 3rd. the japanese lexus is as good or better than audi.....But wait..... Germans are supposely the best
U want bmws go for older 3's or M3, Mercedes go for AMG, the best all rounder right now is Audi... Their new cars are impressive!
