^^^ Thats your best bet mate , Ren UK will tell where it was sourced from . It won't affect your insurance if it is an import as its basically the same car as the UK cars , with the exception of having no window etching , no alarm fitted as standard and no locking wheel nuts . Big deal eh , the cobra alarms fitted as standard only have an 18 month warranty iirc , get an aftermarket like the Toad and it comes with a lifetime warranty .
I'm on my second import and have a Toad 850 cat 1 alarm fitted which works off the renault key fob .
And when you come to sell it , it " will be " worth just as much as a UK car despite what some misguided people might tell you . I sold my 172 for the same price as simliar UK cars on autotrader .
And if your insurance company has your vin number they will know its an import , well Adrian Flux did anyway .
You say you still have the warranty remaining ! Ask Ren UK if you still have any of the AA assistance remaining , if the car came with a full 3 year warranty it should have come with 3 years AA assistance .
