The 2007 Z4 Ms are mechanical carryovers from 2006, adding only a tire pressure monitor and having the subscription period on cars fitted with the optional BMW Assist and Bluetooth System increased from 12 to 48 months.
"This is my 5th BMW, all have been great cars. This one is my favorite. BMW made a winner here. Amazing performance but still docile in town. The torque range of the engine is wonderful, pull away in any gear with ease or drop down and leave the traffic behind. Handling is next to none and brakes that are out of this world. You can drive it as a lazy man or a wild man, it just comes back for more. I have owned the Porsche Boxster S as well, very good car as well, but I love the Z4M over it."
"If you like the styling and the firm ride, this is a top-quality roadster that holds its own anywhere. About 23 MPG from the beefy engine, great handling, good trunk space--a highly civilized sports car."
"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."
