At the exact same time I was out thrashing the BMW 135i coupe around every offramp I could find, Mike Hanley was cruising with the top down in the new 128i convertible. The weaker of the two in the engine department still packs some punch for the size of the car, and Mike found it to be quite a good convertible in its own right. Of course, like the 135i coupe I tested, Mike was a bit flabbergasted at the price tag, which was well north of $40,000.
