Facebook has to much CPC! incrasing every day

hey all i notices something in 2 days of my facebook marketing. i stated with an ad on an auto niche it had 0.75 cpc acceptable now over 2 days it has sugested bid of over 2$! i cant aford to pay that much if no conversions. and if i keep low bid of 1$ no clicks... can anyone guide me how to lower cpc? if people likes my add is that benefic? what about if he hits close button on ad?

any sugestioons will come in handy. i wont hesitate to hit thank you.

the better your CTR is the lower the CPC.
