I am sorry I have not bought at least 5 Z3s. Of the 52 cars I have owned in my life this is my favorite. When the car first came out a friend let me drive his 1.9 around Elkhart Lake and it was a ball, albeit under powered for that track. Then I bought the regulatory Boxster then an SL 500 plus others. At last I found a pristine 1997 2.8. Wow, this car is so well balanced that it makes even an old timer like me look good in the twisties. The 2.8 engine is wonderful. Lots of torque and smooth. Yes, I know the M; to me the M has so much power for the chassis that it is, Corvette like. I will keep my 97 for a very long time even if I find a perfect 2002. Enjoy!
