2003 BMW Z4 Convertible 2.5i 2dr Roadster (2.5L 6cyl 5M)
brand new 15 year old Z4
 Probably too soon to rate it since I have had it for only a week, but, the car with only 23k miles (verified) feels brand new. The sound is great, the punch is great.  The ride is not as harsh as I feared. It's certainly not '55 Buick either. It's a little tight, but much more comfortable than Miata that I didn't buy because of the fit. When I had it inspected the guy in the station said, "thanks for bringing that car to us." First time that's ever happened.  We'll see how long honeymoon lasts.
