I just took delivery of my new Z4 on May 12th. So far, I have only managed 245 miles on it, none with the top down so far. I live in the desert of Arizona and it's just a bit on the warm side. Forecasting 117F next week.

I recently completed the lease of a C63s. It had a few "modifications" and was a blast to drive. Alas, there are so many cars and so little time. I have never owned a BMW before but have always been fascinated by the Z3/Z4. So far, I am very pleased and I can see this becoming a long term vehicle for me. I configured and ordered it exactly the way I wanted it. I ordered it at the end of January and it was delivered in mid-May. It probably would have been quicker but the transport ship got caught in a block-up of the Suez Canal and was delayed getting to the port in Germany.
I am looking to add a few modifications to enhance performance; primarily in the exhaust and air intake areas. Any recommendations and/or advice would be greatly welcomed. Thanks again.
