I can neither confirm nor deny that the following occurred, but here's a story that you may all find interesting:
On the way home from the cottage, there was an idiot behind me with his high beams on. I pulled over to let him pass me, but then he slowed WAYYY down. To avoid this from continually happening, there was a flat, straight section (80km/h zone) and I took my opportunity and passed 7 cars in the Corolla. Topped out at 140km/h and had no issues passing.
With that being said, I maintain that if you're buying a car to track, then you should maybe consider the stock times...but short of that, the minuscule differences between the CLA, WRX, S3, etc. as far as performance goes should not be the deciding factor. Liveability should be.
