18" Ford Racing Cobra R 4 lug?

Met a guy last night on my lunch break and he told me he had 3 Chrome Cobra R 4 lug wheels with tires for sale for $800. Sounded like a deal to me but when i tried to look them up on the internet to see how much they went for new, couldnt find them, only size i saw was 17" in 4 lug. Is this guy giving me a load of b/s or can i just not find these on the internet? also would i have a problem fitting these into my wheel wells, especially the front, if they would rub during turns.
Thanks in advance!!

eh.....thats what i was afraid of, glad i didnt get gyped though, thanks for helping me out
