I had experience with arosa 1.4 tdi, well, it pulls sporty but 3-cylinder engine makes great noise on lower revs, especially outside. When owner opened the bonnet I thought there is something seriously wrong with the engine because it was obviously noiser than my passat b5 which is tdi, it sounded more like crapy golf mk2 1.6 d - horrible horrible horrible horrible generaly, I prefer more arosa's front lights than basic roundy on lupo, except 1.2 tdi lupo which is prettier on fascia area than other lupos, not to forget better interior, especially dashboard
