Here, everybody knows its existence, because "Zoé" is a very used French first name, and many groups made petitions to prohibit Renault to name this car "Zoe"... They had the same problem with the Mégane (and a little with the Dacia Logan) ;)
Strange, I don't see any problems with a car model named like a first name. We also have one: Fiat Albea makes "fiatal Bea", which means "young Bea".
Seat has two embarrassing names, luckily Seats weren't imported here that time: "ronda" means ugly and "fura" means weird. The Hyundai Getz was sold for a short time as "Hyundai TB Get", because the original name sounds like "geci". (The combinations GC*, GEC and GGC were banned for the same reason)
Okay we don't have that problem often in Germany, only with the Mitsubishi i-MiEV, because it sounds in German like the word "Mief" which means bad smell.
Helvetics Mégane is a very common French first name, too (I have 2 Mégane in my class), so now the name "Mégane" is more associated with a car than a person...
