note the high-mount rear-view mirrors....
obviously, the third brake-light is an add on, bu the trunk and taillights seem like they ought to be pretty obvious to someone who knows...

The GF and I were picking up some hay for the sheeps today, and we ended up behind this vehicle on US-RT2 on Grand Isle, At first I thought it was a Peugeot 403 (ala Colombo) but despite the profile, the tail-lights and trunk are wrong,.. can any opponaut identify this (probably) French (almost, assuredly European) vintage soft-top?
