I've got a Peugeot 106 Rallye in real life, the car in-game handles quite the same. I'm loving it. The S16 is a bit faster (and 16V instead of 8V) but also is a bit heavier.
In-game I've got a 106 Rallye with the same mods as my real-life car (I'm looking for the Indigo Blue paint though!) and an S16 modded to 200+ HP really low and stif. Real fun to drive. For an FF car I mean.
