I've been looking at Corrado's all over the place and they are really cheap at the moment. Plenty on Ebay for sub 1k. Albeit many of then are 16v's When I was looking for mine 2 years ago prices were crazy!!! I was planning on selling mine but I have decided that I will spend the little bit of money thats needed to sort out a few little issues on it.
It's not that they're so cheap now, more that they've found their real value, many are a bit rough around the edges now and I'm sure the decent ones will still fetch good money
would expect the 1.8 16v ones to be uber cheap due to poverty spec engine compared to the other models considering its a heavier vehicle than a mk2 golf
