The 4.8-liter naturally aspirated V10 in the 2012 Lexus LFA, already a legend as far as engines go (co-developed with Yamaha) is an all-time engine hall-of-famer. Famed for its incredible 9,000-rpm redline, incredibly sharp throttle response and spine-tingling note from the exhaust system, the 1lr-gue for sale is the most refined forms of mechanical artistry at its very best. Whole engines that you can actually buy are very few and far between, usually from special collectors or motorsport rebuild programs.
