Well I don’t have a Z4 but I have a Z3 and I don’t know much about it’s mechanisms I just want to share my views with you on it’s look and what I think of it......i think BMW Z3 has a very very sexy look, it is a german car... it’s poster it’s colour it’s back it’s doors everything has got a very sexy feel in it.......it is a two seater car bottle green in colour has beige lather seats it’s very comfortable........ when I purchased the car newly and drove it on the high way every one just used to stare at the car I wonder use to feel like a star the car was my first car I purchased it in instalment.for 8 months i’m very fond of cars...especially jeeps and sports cars...it’s extreme mileage I think guys who are in love with cars like me should buy this one you will be very happy with it well I drove the full kuwait city till the saudi border with this car it’s just fantastic I like my car very much because of it’s look and it’s mileage and it’s quite funky........ well I am very happy with this car
