I just thought I would throw in my 2 cents... I drive a Predator X11-08 here in Ottawa, Canada and I have never had an issue getting parts for my car!
I am very proud to run their car here because I like to be different.
Sure it may take a while for them to get me an e-mail response but I expect that, as I know Xtreme is a family run company with only Yanina and Lewis doing all the work.
As for price, these are not mass produced units that are molded in china, so dont expect a china price!
You should see what the exchange rate is from CDN to GBP!!
