Most of us have seen vehicles on rotating turntables at auto shows, but there’s also a practical side for the public. San Diego-based company Carturner builds its patented stainless-steel turntables to be handy for parking in tight driveways or in garages where maneuvering is difficult, if not impossible. There are also professional applications, such as for commercial photographers. Installation — indoors or out — is a relatively simple process since the 15-foot diameter unit sits on top of your driveway or garage floor. Prices start at $12,000 for the brushed or powder-coated finishes, and $13,000 for the mirror-finish version, and includes programmable wireless controls. Shipping is extra.
