Hi and sorry for my bad english but in france there is nothing about this wonderfull car !!!!

Of course you're welcome here. You might also want to join G20.net (www.G20.net) for more information on your car. The Primera handles so well due to it's independent multi-link suspension. there is a lot more info on G20.net about this car. Hope this helped, sorry for the late reply...

i love my G20.. the handling is absolutely impressive. I knew about this car.. what it can do... that is.... handling!!! I planned.. and saved money so I can buy this car and I did... got one. I always out-run Honda, Mazda, Toyota in the corners. The power is very smooth too, love that high RPM.
