Not long ago I was on a school trip. During a walk in a city called ToruĊ, me and my friend saw an old car, it was called the 'Isabella Coupe' (as far as I remember). The plates were german (some Seat car dealer from Bremen). I've checked in the internet , but couldn't find any info on the mystery car

I ain't got any pics either. Can any old-car fan narrow the search down?? I'm just interested how rare it is.
