Nope.
One of my female friends in 6th Form years had one of them: there was a dead straight, slightly undulating stretch of road near us (southbound into Watford from Hatch End - ish?) where - if her car hit the first undulation at just the right speed, and she kept the speed constant, the suspension got into some kinda harmonic cycle, and it was like a tots fairground ride for the better part of a mile
But - no - the car my mate had was more upmarket, mebbe aspiring to the nascent VW Golf market. By its looks it was very definitely a child of the DS fambly (and OBTW it had hydrolastic suspension), and was very aerodynamic, barely any wind noise even at high speed, but with nice curves, and none of the odd rearward angles of the Ami posted above by
@Joker62 , nor the slightly 'I've been stepped on' look of the original DS.
I'm kinda wondering if it was a 'UK' only model
