BMW 1 Series TII concept

I am so in love with the 1-series. This 1-series Tii concept looks so nice. Ultimate daily driver with back seats that I need so badly when I go out. I be more than happy with just 135i in white and black lip spoiler.

I have not been excited about a newer car coming out for years. This one is giving me that I have to have it feeling.

Simple ECU, Intake, Exhaust, Cooling, and other upgrades have lead to 0-60s in below 4.5 out of a 335i. Some even claim at 4.0 flat. Imagine a 135i. First upgrade would be an LSD though IMO. Sounds like a fun car!
