The problem with questions like this is that your always going to be advised to go for the car that the poster is driving or even sponsored by.....
So here goes...
Pred X11 08!!
but seriously they are both very capable cars and both something slightly different from the norm. There is plenty of support for setups for both cars. The pred has a designated forum which might be worth a look (
www.the-pred.co.uk) and ofcourse there is always support available right here on oople in the team xtreme section.
I'm sure you'll enjoy whichever car you opt for, but if you do go for a pred feel free to ask questions in any of the forums.
Cheers
