That though they may share many parts with other more widely available Toyota and Lexus, some model specific parts are simply not available. Cam belt, water pump and bodywork may be an easy fix but I was very close to getting a Soarer earlier this year and due to a faulty airbag ECU the car couldn't pass an MOT and was therefore only worth the scrap value.
All that said, if you do get one I'd love to see it. Cam belt and water pump cost would be around the £400 mark I assume.
