Owned the car since 2004 has now 82,000 miles, performed well under warranty, had to replace the motor for the convertible top at 42,000 mi and now again at 82,000. both times the elec. motor short circuit due to run off water that enters the plastic housing where the elec. motor sits in. The water can't drain and the electr. motor will rust and quit. Very expensive repair, poor design. Car handles great, fun to drive on smooth roads but noisy, and potholes are deadly and my wife hates to put on her make-up while we are driving, rough ride
Styling, performance and great trunk space
Spoiler too low, lousy cup holders, needs more attention to detail, paint is coming off on interior door handles , plasic is cracking on arm rest and all seals around the windshield need to be of better quality they are all cracked
Very nice and fun to drive, however when the temperature gets over 80 degrees the power electronic steering stops working. This is a known problem to BMW (bulletin # 4515500-02) and a safety issue but they want $3000 to fix it. - So much for German Engineering, maybe it never gets above 80 degrees in Baveria!
Power Roof, without a doubt the best I have ever seen. This roof goes up or down and locks in 10 seconds or less.
Need to steer it! BMW should issue a recall before someone gets killed and they end up like Toyota.
Shortly after purchasing it used at 59,200 miles, the coolant light came on so I filled it up when the engine was cold and it continues to leak whenever the coolant expands with a hot engine. I'm guessing the coolant expansion tank is cracked. Other than the above mechanical issue this car draws a lot of semi-truck drivers attention and praises and other people on the road also. It feels like this car has sticky glue on the tires during fast turns. Manual 6-speed transmission shifts wonderfully. Not the fastest car on the road against say a Ford 500GT or any other hot rods but this Z4 has the right balance between styling and performance.
Open or close the soft top automatically in less than 15 seconds. Driver & Passenger heated seats (including the back of the body). 6 speed manual transmission. Flip-Up in-dash navigation screen & car statistics monitor display.
Have yet to fix the coolant leaking issue... my Z4 has to filled once every 40 or so miles driven. Also, the lack of interior storage is my pet-peeve. Only enough storage room for my pack of Orbit Gum next to me.
If you buy these cars, expect to shell out big bucks for repairs. We have an extended warranty which so far has been of no use because of water leakage. The top wouldn't open because of a leak. BMW at least paid for labor, parts still cost us 800.00. Now the wipers stopped working. Some part cracked and water again somehow got in. Going to cost 1100.00 to fix and again, it's not covered under the warranty. Great looking and handling car, but poorly built. Will never buy a BMW again.
Fun to drive, looks great, handles great.
How about making them more waterproof! Poor design quality on major parts. Warranty should cover more-wouldn't bother getting it again.
