So collected the car on Saturday morning. Having now spent some time in it I am very impressed. I drove it into work on Monday (Northcliff to Sandton and back) and although the silence is weird, you adjust quite quickly. I then drove the 8 to work on Tuesday, and to say the experiences are worlds apart is probably an understatement.
The acceleration is absolutely brutal. Although the 8 and the i4 are similar in power, the way that i4 just fucks off is mental. Sorry, that was the only word I could find to adequately describe it.
It got caught in rain on Saturday so needs a wash which will happen this Sunday, then I'll post some updated close up pics of it. Both my wife and my son are thrilled by the acquisition. And admittedly, so am I.
