Simple facts for me (on topic here) are these;
The only thing I hear from people on this site are moans and groans to do with something that has gone wrong on their Renault. Mine, luckily, never properly failed on me, but boy did it cause one or two problems (3 engine wiring looms replaced under warranty in the first three years for starters).
Now the first thing that has started with the 200 is the fact that Renault appear to leave iron filings throughout the car . . . that rust . . . and cause paint defects. Small? Yes. But what else is hiding!
A friend has an R27 and has had so many issues, regardless of how small they may be.
Have a look at the mini forums and yes, there will be issues, but nothing like the number that Renaults have.
For me, I would buy the GP any day of the week, if those were the only two choices.
