I'll correct your capitalisation, because I have nothing to do with my time. The company spells their name '9ff' with lower-case letters. As for Ruf, it is the last name of the company's founder, Alois Ruf - which means there should be no capital F there.
Hopefully, you'll forgive my tutoring
because, apart from that, you're completely right. It
is a 9ff GT9.
