I test drove a number of cars before I bought my 1.2: Citroen C1, Daihatsu Sirion, Skoda Fabia, VW Polo. And even though the last two are built around the same platform... the Ibiza was just more comfortable and so much nicer to drive. (These are comments I've heard from other SEAT owners/passengers as well.) For all its imperfections, that won me over --- it's so taut and responsive and fun.my missus then bought a 1.2 mk4 and I ended up driving it and thought how lovely is this to drive and immedietely researched the more powerful version.
This review from evo isnt too bad, doesnt praise the car but doesnt slate it either!
