There are quite a few on the net now for sale. Though the asking prices for neat ones are quite steep, the highest price I saw is R169k, best one for the price was R110k pre-facelift though. I would steer away from the bargain buys that have no service history and somewhat have signs of neglect.
Choose one with a new condition roof.
I own one, and it's a pleasure to own and drive. Though I must advise you,
Since it's a cabriolet, the handling is not as the sedan or coupe. It's also thirstier due to more weight.
I doubt I'll sell mine soon. These motors go on forever if looked after.
