Shouldn't be too bad. I drive mine from Chicago to Lexington, KY (~400 miles) a half dozen times a year and enjoy the trip. The bulk of the 22k miles on my car are road trips like that.

I think it would be very fine. I took my Z4 on a 2500 mile trip last year as a driving vacation. One day I drove for 8 hours (with only short bathroom and food breaks) and I never felt cramped, tired or anything but pure enjoyment. My 6'2" son was along for the ride...and he also never felt anything but pleasure. Go for it!

Mein Auto: Z4 Si, 330i
I've got an 07 Si and threw on the M front Bumper. I like the Si better. It's a very quick "cruiser. " That being said it still goes around a corner in street driving (Think tail of the Dragon or Six Gap Run) as well as an M.

http://tailofthedragon.com/pdf/Brochure2011_LowRes.pdf
http://www.sixgap.com/

Until the CDV mod is done to the M it hangs with it for the first 2-3 gears. 0-60 mph its about a half sec behind the M. Considering the M is a 4.9 sec car thats not to shabby. A fully decked out Si is also much fun to drive. With DTC on and good tires/brakes it is forgiving. Paddle shifters are pretty responsive and smarter than you to prevent over-rev. Not bad considering its an auto tranny. Not much you can aftermarket on the engine bang for the buck wise. If you want 500 horse aftermarket the M is the way to go. All that will get you in the Si is a huge bill for a supercharger and a blown engine. Finally, I luv the Si wheels
See for yourself, got the old and the new:

Mein Auto: 2006 Z4 3.0si
My decision was easy. I had an overpriced AMG, overpriced S2000, appropriately priced 350z, and a great price on a Z4 3.0si.

I drove the Beemer first and no-showed on all the other appointments.

For me (I drive a Honda element which I've modded and tweaked as far as it can go), anything is a thrill to drive and the si has been amazing. I don't push it to the limit, and will always know that it has more power than I've used or need to use. The sport rims and red leather catch attention everywhere I go, and getting an M wouldn't have added anything to the things that are important to me. I drive slow so people can take a look as I drive by, and if you want to catch their attention early, drop a gear or two and spend a few extra cents on gas. The exhaust tone is very controllable.

Well...all is done....'06 Z4M black/black, 41K miles, 6 sp manual....I am tickled to death....much quieter with top up and on interstate than I thought....The ONLY small thing is the rough shifting of the manual, it seems to be real similiar to the 46 M3....I guess I was spoiled by the 335...Thanks, WC

Congratulations! IMO, doing a CDV delete on the Z4M is mandatory. You'll find lots of threads here on it, do a search. Let's just say that for the first couple of months after taking delivery I thought that I had lost 40 years of knowing how to drive a manual. Paid dealer something like $100 to remove the CDV and the car shifted like I knew it should.

CDV = Clutch Delay Valve or "clutch lock valve" in the parts list. Do a search here on CDV and you will turn up lots of info, it's been discussed here to death. Some people replace with a bored out "fake" valve from Zeckhausen or BAV. Others, like me, just eliminate it completely. Some links you may find useful:

There are a few companies that make a nice braided clutch line that removes the CDV, I got mine through Turner.

Dolphin, Congratulations! When I bought my 2006 Z4 3.0 si I didn't even know they made an M. You're right. You would always been looking back. Good choice. I wish I had 75 more HP but I love the automatic and the fact that my wife loves to drive when we go on road trips.

Well, I was having some PPD(thats buyers remorse) after I got the car on Saturday...afraid I had made a mistake selling the 335. My new '06 Z4M is Sapphire Black Metallic, I was a little concerned about the paint because the M badges were faded, so I spent Sunday washing, applying Meguiars SwirlX ( that is a job, but really works), then a coat of Meguiars Gold Class Carnauba Plus...unreal, beautiful....I don't think this car has ever been waxed. Once cleaned and waxed the paint job was great, VERY few chips, etc....its almost like the car was not well cared for but was parked in a garage..The interior was dusty but pretty much perfect.....the car is absolutly beautiful, wish I knew how to post pics....anyway, yesterday I took the car for a drive, and I'm really happy....Thanks ofr opinions, etc....WC

Is it fair to compare?

I have now driven the '06 //M and an '11-3.5Si. I think if money was not an issue I would definitely prefer the 3.5Si. The car seems to be developed to the point where it's performance exceeds what I could accomplish on a public road... Just like the //M.

I didn't look, does the '06 //M have the S/SS mode selector?

I still have to figure out how I am going to be able to drive any Z throughout a winter with snow and LOTS of rain.

It has a Sport button that removes the delay between when you push the accelerator and when it kicks in, for lack of a better term. I think it really makes a difference. Has has much more of a kick in the pants when you hit the gas.

I prefer the looks of the E85 over the E89. The deal breaker for the E89 is trunk space. I have a couple of friends who cannot take their 35i's on any weekend top-down road trips simply because of non-existant trunk space.

Buy an M and don't look back. In my 10 years of owning a Z and being on various boards, one constant holds true. The owners of lower cars tend to start out stating they are happy with the performance and within short time, after they have acclimated to the car, always seem to want more. By getting an M, not only are you meeting most of your stated needs, you will be forestalling the urge to modify for performance all the more. In terms of price, the Z4 M roadster are an absolute steal right now. Prices are going to be falling in the next 90 days as the sunny season comes to a conclusion and folks want to sell. Get all the car you want so there are no regrets down the road.

Well I have had more fun that a person has a right to be fixing my M up the way I wanted too. I owned a 2004 Z4 3.0 which the wife and I enjoyed but it spent more time in the garage parked than this M has. I recently had the opportunity to put my car on a dyno and got a run out of it. 270 RWHP and 234.12 Max Torque so it's got plenty of humph for a stock M. I don't think you will regret your decision one bit.

Best of luck.

Damn.....I wish now I had gotten an M (coupe or roadster)...but at the time, there were none available, at least in this area. I am really torn...I love my 3.0si roadster, but then too, I love some of the M coupes I see nowadays. Maybe I should just be satisfied, huh? I saw a black one today...wish I could have met the owner.
