My sisters got a '98 R 1.4 CL and it's a nice little car, very nippy. For some reason everytime I drive it, for more than say half an hour, I end up with a sore knee.
Problems to date are; rust in funny places, seized rear wiper, leaking drive shaft seal, rear wheel bearings whining and the aerial fell to bits.
Otherwise it's a good car. If you get it check the pollen filter, as they seem to be overlooked.
