"I bought a used 2003 2.5i version of this car and even though it is the smallest engine available in the US I still love it! Its reliability has been good (with the exception of the convertible top needing replacing), I've gotten looks and comments from people that have been mostly good, and have been on numerous road trips with it. There are a few nits about the car though. The run-flat tires combined with a rock hard suspension mean that you'll be thrashed about on anything but smooth highways (which in America are rare to come by, least of all in my city, Seattle). The electronic steering can seem sluggish on bumpy roads and the car's true acceleration potential is hindered when not in sport mode. Lastly, it's not the most practical but if you're buying a two seater convertible, you're not aiming for practicality. If you can get past these nits, then you'll love this car. I plan on keeping mine forever."
"I just got my z4 and i am thrilled each time i drive it. i just step into a different world whenever i drive -- the top down, the sound of the wind and the engine is a very exhilarating experience. sticks to the road on turns, very easy to go fast, the top goes down in less than 10 secs... although some people find this takes too long, for me it's just fine. all my colleagues at work wanted to get one when they saw it. i got a loaded z4 (premium and sports package, leather and heated seats, xenon headlights, etc.) and i feel like a princess in it :) the heated seats are also a plus, the auto dimming mirrors and automatic headlights. i am also impressed with the technology of the run flat tires, and the dynamic stability control and dynamic traction control where the car modulates engine power and applies brakes individually to tires to help keep the vehicle under control when it senses under or over steering... this car really knows how to treat you right!"
"I have had this car for several years and absolutely love it. I have the Z4 Coupe variant and keeping in mind it is a sports car not a luxury crusier it gets you there fast and in style. Not the easiest car to enter or exit but if you are buying a car for that purpose an SUV is the better choice. For performance, handling and looks it does not get much better than a BMW Z4!"
Pros: "fun roadster, handling is tight, great looking"
Cons: "run flats can be pricey, cup holders are flimsy"
Likely to recommend this car? (1-10): 10
"Bought the 2.5 manual Z4 used with 27k miles on it. There is nothing practical about it, but that is not why you buy a Z4! Nothing but fun with it, no mechanical or electrical issues. Absolute joy to drive hard with the manual. Very fast convertible top (< 10 seconds). Biggest hassle was replacing the cup holders, which were an add on for the U.S. market. I don't think there's a better looking roadster out there!"
