Narrative:

Left for a local flight and approached jvy. I made a call on unicom and 2 other aircraft were in the pattern. We sequenced into the pattern without problem and on final saw several cars at the approach end on the side of the runway 18. We extended out and touched down 1000 feet beyond the cars; we then took off for another touch and go. After a second landing and as we continued downwind; we saw another car driving south down the side of the runway. Another plane was turning base to final.we announced we were leaving due to the cars. There were no markings on the runway and no announcement on unicom (there are 2 active fbos on the field). After I landed I checked the FAA website for any NOTAMS and found none relevant.this was potentially a problem as several planes were calling inbound on unicom. I should have rejected the first landing and should have used another runway or returned home. The airport should use markings and someone should have been on unicom to alert aircraft of their presence and intensions.
