That's what I said to the LAST guy that just posted the idea about crafting a targa roof on a Capri...which was just a couple of weeks ago.
Personally what do I think? The Capri looks pretty cool as is (albeit the body could use a little rounding), and I think that kind of modification is a little extreme. But I know everyone wants to chop up cars in the name of individuality, so good luck on your project! Do you have any sketches of your ideas?
