2013 BMW 1 Series Convertible 128i 2dr Convertible (3.0L 6cyl 6M)
Traded a Z4 for a 128i Convertible
 I bought a 2003 Z4 ten years ago and thoroughly enjoyed driving it for 55,000 miles.At the age of 52, it was a great purchase.At 62, with bad knees, and 6'3", it became more difficult to get in and out of.And, being a roadster with a small trunk, it wasn't good for more than a quick overnight trip.So, we traded it on a '13 128i convertible and so far, it's a wise decision.Had to special order it since I wanted a manual transmission and was willing to pay only for the options I wanted.Only 1000 miles so far, so it's too soon to determine reliability.The fit and finish is typical BMW qaulity and the engine and transmission are smooth.UPDATE:  I've now owned the 128i convertible for three years.  It's got 16,600 miles, all trouble free.  It's still fun to drive and I got another compliment on its appearance just the other day.  It's Vermillion Red with a black top and tan interior.  This is not my primary driver, but now that I'm retired, it does get driven more.  It's a good combination of being a true sports car, but with more room than a roadster.  The 2 series BMW should provide the same benefits since it's basically the same car with a different number.
