l wanna buy a renualt clio v6 but obviesley thear is no dealers of renualt in USA ! Why dont we have renualt dealers?

cuz we suck.
theres a ton of European cars id buy if we had them here.

because the republicrats do not like the FRENCH

There are different vehicle standards in the US then in Europe. Renault, as a company, would have to retool their vehicles manufacturing plant to produce cars in line with American standards and that would be a very expensive proposition. The Renault company has obviously made a decision, through a cost benefit analysis, that the risk of a capitol loss is not worth the potential gain by creating a vehicle for the US marketplace.

we used to, but nobody bought them and the dealers went broke..

Because there are laws against selling crap

We used to get Renaults, Peugeots, Citroens, Austins, Rovers, Fiats, Alfas, and a bunch of other low priced European brands. Then the Japanese came and killed them by selling high quality cars. Driving a Renault is like living on a flat earth. If you're really that lacking in automotive sense, buy a Nissan. They're the same thing, just with somewhat less bad quality and styling.

Renault r not interested in the American market mainly because Americans generally dislike small, pokey, rattley little cars & prefer huge, tank-like, gas guzzling monstrosities like S.U.V is which get a bad press in Europe.
Also, due to the incredibly strict U.S Emissions regulations it is hardly worth European manufacturers exporting to the U.S because once the cars have been deemed ''safe'' by legislative standards they've lost almost all their power & their styling & aerodynamics r compromised by oversized ''safety'' bumpers.
Dodge used to be owned by Renault & Mack Trucks still r although Renault Trucks Europe r now totally owned by Volvo-Scania which means they now have a total monopoly in North America.
If u really want a Clio V6 I'd suggest talking to a specialist car importer or perhaps try buying one online via eBay but u will have to arrange the shipping yourself if u follow that route.
