Everybody has an opinion about different cars, I just liked the Punto, it ticked all the boxes I wanted, small, Italian, diesel, and less than I was expecting to pay. Plus as you've said Gibbo, research is a good thing. After driving around town for the first 100 miles, I took it to London and back with a millers fuel additive as well. So far it's done exactly what I wanted it for and as long as it lasts the year, I'll be happy.
Thanks for all your advice, at least I'll know where to come for my replacement!!
