+fireamx, thats a funny one!

I'm all for a secret handshake!

Anytime you buy a car, you should have a competent mechanic go over it in detail. Of course, you have to find a competent mechanic first! You might suggest those who race, track, abuse, or otherwise think they own a pocket-rocket also provide the next potential owner copies of all their escapades. Surely the new potential owner will want to know the cylinders (and any other vital organs) are about to drop out of the block?

My XF runs great (so far) on a mixture of 89 and 93 (much more 89 than 93 I might add), just waiting for more miles traveled! After a few tankfuls I will hook up my OBDII and re-evaluate 89v93. I look forward to having this car with its original motor until I die or it becomes a classic worth thousands! (Hahahahahahahaaaa)

BTW, I just scored a 1:18 scale Maisto Special Edition XF Coupe ma41140k(s) brand new for $24.75 delivered. It looks GREAT! Although I will not be using 93, 91, 89, or 87 octane in it, it makes me run like I have avgas in "my" tank!
