THE B-SERIES started life as a no-frills, functional workhorse when it was lauched as a B1500 in 1970. Times have changed and so too the styling chosen by Mazda for the new-look Bravo. Gone are the hard vertical side panels and box-like forms of the past. Most noticeably. it's the curved drop nose of the bonnet, the pressed "V" indent that runs the length of the body and the swelled front wheel arches that gives this light commercial a modern look.
