Was gonna do something similar myself. Couldn't decide between fiesta mk2 or escort mk3. The fiesta's are light and go like stink with a quick engine in 'em. But i prefer the shape of the escort !! So i decided on a rs1600i, started looking around for one, then come across a s1 turbo with 77k one owner, which i bagged for £3500 But still like the idea of a quick normally aspirated motor stripped !!!! Gotta say go with a mk3 escort cause i love the shape/look of 'em !!!!!!
