This One-Family-Owned 1973 Porsche 911T Targa features a distinctive removable roof panel and comes with a 2.4-liter flat-six engine paired with a rare five-speed manual transmission. Originally purchased new in California by the seller's father over four decades ago, this classic German long-wheelbase model sports an era-authentic design and is now based in New York after being loved as a daily driver until the mid-1980s before entering storage from 1998 until 2014.
