This is my Audi A4 allroad next to my Z4. I lucked out with the license plate for the A4: COASTER. The previous owner of this plate apparently didn't renew it, so I snapped it up while it was on the available list. For the Z4, the license plate, AIRTIME, is a roller coaster term for rising out of your seat, and it seemed like a good term for a convertible car, too. For the longest time, people simply assumed I worked for a cell phone company. It's only coincidental that I subsequently got jobs working at Cingular Wireless/AT&T and at T-Mobile!
