[esqu1re]

I daily drive a M coupe. The suspension will be much harder than a 335i, and will feel much smaller / darker inside. Acceleration is no faster than a stock 335, but it feels faster due to its size / sound.

You do get a lot of compliments and/or questions when stopped, so if you want to be incognito, it may not be the best car.

No real way to get more power out of the engine unless you go with a supercharger option. Headers and tune is pretty much the extent of modifying the n/a engine to make more power. . .

I think the Z4M is a much more "focused" car than a 335, but comes with its own set of limitations. It's not very comfortable over long ranges, and its thirstier. There's little room inside for gear, and the infotainment system is two generations behind the current one.

I still love mine as it puts a smile on my face just about every time I drive it.

Good luck w/ the shopping!
