"It's absolutely fantastic to see it sitting there behind the police station," Costello said.
"It's worth all the sleepless nights making sure the paperwork was done."
She wanted to thank the patrol's sponsor, the constable and the businesses that found the car, painted it and installed its electrics.
Waverley's community patrol is a team of 10 volunteers. They patrol two nights a week, for three to four hours at a time, working in pairs.
The team gets information from police; for example, about cars police are looking for.
Costello and patrol co-ordinator Doug Rosewarne were out on Friday night and did 109km in the Vitara.
The patrol deals with wandering stock a lot, and it keeps an eye on events where there is alcohol. Capturing a calf on SH3, with trucks pounding up the Whenuakura hill, would be one kind of tense moment. Others might involve people, but the patrol doesn't get up close.
"We sort of just park," Costello said. "We sit in a street where there's things going on. We don't hassle the people having parties. They're entitled to do that. If they come out onto the road and start fighting we let the police deal with it."
