My wife had a Renault 18 when we met. It also had a soft ride. It actually cornered pretty well once you got past the feeling that the you were about to scrape the door handles...
If only I could have my Citroen SM or CX Pallas today I wouldn't buy another car. The CX and the MB W123 diesel were the most dependable cars I ever owned bar non. The SM could go on the nerves a bit but man what a car.
