The 3.0 is probably the best daily driver - 17 inch wheels and tires will offer a better ride and the slightly smaller (detuned) engine good gas mileage.

The si will be a bit more harsh and the wheel/tire combo of 18's more fragile (some come with 17's) but otherwise a good DD

The M is in a different class - it's a lot of power for a lightweight sport car and the gas milage really suffers. However, it's the highest performer of the three, but that's academic, you'd only exploit it at the track, and you'd need a LOT of talent to exploit the M's capabilities well.

IMO, either the 3.0 or Si would give you more than enough handling and thrills for street driving, return good mileage and be comfortable and livable for everyday driving.

Your choice, go drive'em and enjoy.

PS: pre 2006, the Si was the 3.0 and the 3.0 the 2.5.
+1 (Can't believe I am agreeing so easily with EDCT!) I use my 3.0Si as my daily driver, sometimes in significant traffic. While the M might be more sporty and fun to drive, I never really considered it due to the beating it would be in traffic. I really like the 18 inch wheels and overall wider feel of the Si VS the 3.0. I also like the look of the sport wheels that come when you get the sport and premium package (which is how many are equipped).

The prices you are talking about seem pretty high. I bought my 2006 3.0si in 2009 with only 17K miles for 28K with a CPO warranty and waiving a lot of excess wear and tear on my previous Z4.

If I were looking at a used Z4 I would look to the new model design for a CPO xdrive 35. My son's xdrive 3.0 compares favorably to my Si, but adding the turbo makes that Z4 a beast with no need to add an M to it. It's already a ticket machine, but if it had the turbo, he might be in jail permanently.
