I have a weekly search running on TradeMe (NZ's local on-line trading site) for "Bravo HGT". Because they are rare here, anywhere, it usually returns only parts common to other Fiat models. Recently something different popped up:
Fiat Bravo Brochure 1996
40 pages + gatefolds, superbly illustrated. Covers full range including HGT. Mint condition.
I bid, won (of one), and it arrived on Friday. It was as good as described, a nice accessory for the car which it was selling.
