The 3MPS as stock is a great car...
I have had no problems with mine and it has done 95000kms of hard driving.
Mine is a Nov 06 build....
As for the HSV VXR...i have driven it...as i was an opel fan and car club member...and its woeful.
Horrible interior and very overpriced....i do like the aggressive styling and wheels tho.
Search for a good one..and you should have a problem...or you can always buy the new MPS just been released.
Happy Motoring
