Wouldn't consider itJust dont get married without a test drive.
I also notice no turbo lag, just throttle lag in D mode only. This car has so much torque down low, even compared with an M3, you may think your M3 had the "torque lag".I've not noticed any turbo lag - not anything different than any other throttle response from other NA vehicles.
+1I bought my 335i Convertible without test driving it since they were not in production yet. And if I didn't like the car when it came in, I wouldn't have to take delivery of it. In my case, the dealer would have had no problem selling it for more money if I didn't like it.
