Rare find, last year for hidden wipers. Check it out, power steering was an option on a 1972 Vette! 1972 was the last year for chrome bumpers at both front and rear, the vacuum actuated pop-up windshield wiper door, as well as the removable rear window common to all 1968-72 coupes. The key activated anti-theft alarm system became standard. The increasingly popular choice of an automatic transmission was installed in most corvettes for the first time, with nearly 54 percent so equipped. This was the final year for the LT-1 engine, rated at 255 hp.
