Bought the Z4 last year to replace my E92 328i. This is my 3rd BMW and like before went through Irv Robinson at Motor Werks of Barrington. If you are thinking of doing a European Delivery, he is the man to talk to (if you're not thinking about ED, you should be). Picked up the car at the Welt in Munich in April and put about 3,000 miles on her driving through 9 countries in 7 days. I was lucky enough to get one of the first 2014's built in March. After a excruciating long wait, I was finally reunited with her at the BMW Performance Center in Spartenburg, SC in July.
Not long after getting the car back the modding began. The stubby antenna and black grills went on the day after I got the car back home, and I'm finally at the point where I'd like to think its just about finished.
