My Sapphire Black 3.0 z3 roadster is 13 years old next month. I have had the car three years and have done very little to it other than give the hood the Renovo treatment and full Swissvax detailing twice a year (hard work but very rewarding), there is slight cracking in the ivory leather but other than that the car is as new!! well done to the previous owners. I also have a 428i M Sport in melbourne red metalic but have to say its the z3 that puts a smile on my face every time I get behind the wheel.
