Ruf's are 100% original excluding the Porsche-sent chassis.

Doesn't seem enough to you?

I mean, Porsche send them the chassis and, everything they work on, then they apply it on the Porsche's Original one!
They are not  CAR CONSTRUCTORS, they are CAR TUNERS!! 

I mistaken the word ORIGINAL...i meant they are not OFFICIAL. They are not official tuners.
They are not like AMG is for Mercedes. You can find the Mercedes AMG in a Mercedes store. They are in their list!

RUF is not Official.
You can't go in a Porsche store and ask for a RUF, maybe they will look at you even badly!

That's why there's no thrilling in comparing a F430 to a RUF, You are not comparing an official FERRARI to an official PORSCHE.
And the challenge between Ferrari and Porsche it isn't something easy "replaceable"!
