For well-heeled drivers, Mitchell & King of Scotland provides a highly specialized line of car-care products. The company bills itself as “the most unique and exclusive car wax artisans in the world” and based on the prices, there’s no reason to doubt that claim. For example, the company’s Ultra wax is blended with 78 percent Carnauba that the manufacturer says is the hardest natural wax available. Each 200-millilitre (6.8-ounce) container comes in a wooden presentation box and is accompanied by a bottle of anti-UV shampoo and “top-up” spray. The Ultra kit sells for a wallet-busting $995 and is available at www.mitchellandking.com.
