General Comments:

Extremely fun to drive, especially with the top down. Enjoy the handling and acceleration. This is by far my favorite car that I have owned. I have always wanted a Z4 and this one has not disappointed. A true sports car.

Much better fuel mileage than I expected is a bonus.

- Com box.

- Center console clips for wood trim.

General Comments:

Owning this car is like being with a supermodel; it looks beautiful, and it is fun to take for a drive, but it will break your heart.

This was purchased as a second car, I've had it 9 months and it's been in the dealer service center over 42 days since I purchased it. I love it, it drives great, it sounds great, it is the ultimate driving machine, but it spends too much time in the shop.

I'd write more, but I got the news today about the shock in the rear that has to be ordered. So I'm quite upset, I have a lot of positive things to say about the car in terms of how great it is, but all I can think about is how I've spent more time driving their loaner cars than I've driven mine. If you like that, get one, if you don't, don't.

I haven't even had my first 10,000 mile service yet and it's been in the shop 10 times. I calculated that 1,000 miles of the 8400 miles on its odometer have simply been driving it in for service. This is not stress free.

Faults:

A bit rattly & squeaky. Bits of trim sometimes emit strange sounds, which can be tricky to pin down. I suppose it's part of the lightweight sports car thing.

Misfired a few times and an engine warning light came on. Took it to BMW specialist, who fixed it. The interesting thing was that the misfire was caused by dirt in the fuel, which meant that the valves had not closed properly, leading to the misfire. The specialist cleaned the valves, and then upgraded the engine software, so that when I switch the engine off, the engine bounces the valves a few times to remove any deposits. (Wow!)

First thing I did when purchasing the car was to switch the run-flats for regular tyres. I bought it in winter, and the cold temperatures on UK B-roads made it tramline badly. I was really a bit worried about it and thought I had bought a lemon. Since the new tyres (Khumo), it has been excellent - taut & controllable, and relatively comfortable for a low profile design.

General Comments:

I think that this car has quite an exotic design, and is the best example of flame surfacing. I think this could even be a future classic, as most people missed this car when they bought a Boxster.

The car has 2 main driving types. Normally it is happy to cruise, and the 3 litre torque means it can potter about a low speeds safely and easily. It's not scary and is mostly relaxing. When you change with the paddles or hit the sport button, things get a lot more lively. It is fast and handles well. You are reminded that this is a FE/RWD car, and at speed you can feel the balance of the car and steer on the throttle. Exciting and powerful enough to scare - so be careful!

The hard top reinforces the design and is worth having for winter.

Practical enough with a good boot/trunk.

The Z3 was a bit soft - and the current Z4 is a bit heavy. I think that this model Z4 is the best modern sports car BMW have made.
