The Phantom Park is a car lift that lowers into a subterranean garage."The nice thing about this is that at the grade level it looks like a regular garage floor," said Cheryl Nauman, an employee at American Custom Lifts. "When you hit a button, another comes up."Brad Davies created the sophisticated car elevator. His shop, American Custom Lifts, is located in downtown Escondido, but he has installed the lifts in homes around the world."We just recently installed one in London," said Davies. "We have one in New Zealand [and] Norway. We have quite a few in Canada."Clients include actor Harrison Ford and singer Britney Spears. Now, presidential hopeful Mitt Romney wants to install a Phantom Park in his La Jolla home. First, Romney will bulldoze the current 3,000-square-foot home and build one that is 11,000 square feet. The basement alone will be 3,600 square feet and is planned to have a Phantom Park in it to store his cars."For the cost of the lift, delivery and installed it's about $55,000," said Davies.The Phantom Park is not just for cars. One local client had a boat lift built into his backyard. The lift is even covered with grass.As for Romney's home makeover, his camp said it is on hold until after the election.
