 Exceptional performance, fun and reliability.  Purchased my 135i convertible in Dec 2008 (good time to buy, great deal, low 0.9 financing). Must say we are a BMW family, and also own a 535i, and previously owned a 330i and Z3 (3.0) so we are biased to the exceptional service, warranty, and purchase experience at BMW. Have put 24K miles on it in 9 months with no problems.  Very comfortable for one or two people, excellent seats and ergonomics.  Purchased this as a replacement to a 2001 Z3 3.0 with 200K miles, so I view the small back seat as extended cargo space.  Smooth, for it's class, on the highway and exceptional on back roads and acceleration.  A true wolf in sheep's clothing.
