Z4M coz it was cheaper and neater than the M3 i went to buy that day.... No regrets, the M3 is great but the Z4m is a tad bit more exciting for me. plus it looks weird in a nice way.
thats why its called the batmobile/batman..check below..same same..kinda![]()
So I have had experience with both. I owned an E46 M3 for a number of years, and now own a Z4 M Roadster (and I've driven a Z4 M Coupe a few times).
The E46 M3 was always the car that I was most emotionally enticed by. I love the E46 design. I love the interior. And I love the packaging of a coupe with rear seats and a boot. It's subtle and practical, but can still deliver the most sensational, visceral and engaging driving experience on a mountain pass.
These are the things that have typically made all generations of M3s compelling.
Outside of the packaging of an E46, the real love I have is for the S54. For me, it's the most brilliant engine regardless of what chassis its placed in. I love the sound (especially with an Eventuri), I love the near instant throttle response, I love the high red line. It makes good torque and still produces exciting peak power at redline. It has this ferocious nature in how it delivers acceleration.
I feel that the S54 is at the center point of the experience (for me) of the M3, and hence it was no surprise that I find the driving experience of the Z4M (Roadster and Coupe) similarly satisfying. I still prefer the overall package of the M3 for the reasons mentioned above. I don't find the Z4 M as beautiful, but it has it's own quirky character which I enjoy in it's own right. I do enjoy the additional convertible aspect of the Roadster which I feel overall adds a lot of value relative to the very minor tradeoffs. I find that the M3 has a more confidence inspiring chassis when driven hard - this is very much a subjective "feel" for me. But I should say that I feel my Z4 M roadster is every bit as competent on mountain passes, just with a slightly different feel.
These days, the reality of the market is such that it's more affordable to find a nice example of a Z4 M (especially a roadster) than E46 M3. That was enough for me to make the switch into a low mileage minter of a roadster and I've been very happy with it. I'll still always be more in love with an E46 M3, though.
Some noticeable differences:
- The throttling is smooth and more consistent in the M3
- The gearbox in the Z4 M is different, and seems less prone to developing a sloppy shift feel
- The rear differential in the Z4 M is different, and they seem to clunk less as they age
- Z4 M doesn't have the rear subframe / rear axle carrier panel cracking issue
It's a very subjective matter, but if I was given a budget that offered the choice between a really nice Z4 M, and an average E46 M3, I'd choose the Z4 M.
100%! Especially the 2001/2002 AC SchnitzerI would actually take a Z3M over a Z4M, just for the sheer craziness of its looks.
The Z4M is the better car, but the Z3M is insane.
