Well we have a clear winner i guess
.
The 120d is great but you could also opt for the 125d ... which has 2 turbos (small and big as the 120 has only a big one) so less lag and more revs ... and 224 hp / 450 Nm.
Is the 1 series available in the US? Diesel ? You could opt for the 125i or 140i
for that matter.
