I have the 2.5 5 speed and at times a sixth gear would be good, the main benefit of just 5 i find if your feeling lazy and just cruising you can leave it in 5th it will pull from below 30 with ease all the way up to naughty speeds. Personally i would go for the six speeder, especially if its the facelift and possibly better kitted out.

thanks for that what i am after is to compare r.p.m at 60 mph between 5 speed & 6 speed

Depends if they are both the same Engine. As the N52 Engine came out in 2006 So would be hard to do a true comparison if the 2005 is the M54 and the 2006 is the N52

Lucky Jim - you're best off posting a question on the Z4 forum, they are a friendly bunch over there so I'm sure someone will know the answer and respond.

The 2006 Si model with the later engine is IMHO better than the 2005 (obv its up on power & torque too)

thanks to all that responded im picking a 2006 2.5 6 speed up this pm although its got a roof motor fault ..due to bmw keeping the motor cool by immersing it in water.

remember the facelifts had 2 2.5 engines, one was the 2.5i (177 bhp) and the other 2.5si (215 bhp iirc) both 6 speed! make sure you get the si for more powerrrrrrrrrr

Nice one Jim
Z4 forum will help you with the roof motor issue - not too big a deal really and hopefully a good bargaining chip for you when you bought it !
