2 litre rwd estate. about 135/145bhp
2 litre saloon fwd. about 140/150bhp
2 litre estate fwd about similar power so they all roughly same speed.
2.5 litre+ estate rwd bout 220bhp up to 300bhp???
a rwd saloon but not like the xrt.
maybe some muscle cars? no ricers etc. maybe base some of the cars on ford granadas (not mk3 jelly moulds) as they are a nice shape to work with and get decent damage on with the roof going up when they are hit. also 2 litres maybe shape them like mondeos/cavaliers/sunny's
