Line-for-line, curve-for-curve, the 240Z is as good-looking as a Maserati Mistral and just about as quick. Japan’s first “modern” sports car, apart from the $1.2 million Toyota 2000GT, changed perceptions about cars from the Far East. Series I cars from 1970 to 1971 are the most desirable; the near-identical Series II cars were made through 1973. Its 151 hp, 2.4-liter inline-6 engine was reliable and strong, proving successful in SCCA racing. In the context of its era and at a price of about $3,500, the Z-car offered more sophistication than a comparably priced MGB. Today, it is a full-fledged collectible and, like some other sleepers on this list, the best ones will cost about $50,000; a good driver, half that amount.
