Motor Trader got one advertised yesterday. 3rd Gen. Manual. Price 16.3K. May seem a bit high but I guess it is up to you to negotiate based on the condition of the car.

Search for "Prelude" under the General Section
From my experience, if the car is really tip-top as advertised, it is worth it, as it is a 3rd Gen 90' Prelude with the facelift lights and bumper (looks like it anyway from the tiny picture, but could be a pre-facelift model, need to check). But as usual be wary of possible misleading ads.
