Where are you based?
If you're down south, besides rare exceptions, you've chance of getting anything RS at all regardless of condition be it Ph1 or Ph2. If you're midlands/north then Ph1 possibly high mileage Ph2.
As with any car, but to a much greater extent with RS Clios, condition and service history will dictate whether it's an enjoyable brilliant little car or whether it's a monthly money pit that puts you off Renaults for a long time.
