The latest Z4 is a base 2.5. I've had 2 Z4 M Roadsters and one 3.0 6 speed. In my humble opinion, this 2.5 with the 5 speed is the most enjoyable. It's always in the power band
I'm brand spankin new here. This is my 4th Z4 and i'm trying to fix the premium/hifi carver amp issue. My car is an early production of 03/03. I found a used premium/hifi amp that's a factory part# but doesn't say Carver. Does anyone here know a way to check compatibility before i buy it? Thanks...
