I can think of the twin cams 16v, and before that the Super Responsive Series on the 4-KC (or maybe 4 AC) engine, can't think of the O2 advantage models specifically though.
A neighbour had a 86 or 87 twin cam until 2015 (rust), definitely sounded nice, but rust took hold.
It pains me when people (like the woman over the road with a near new BMW 3 series turbo something) start the engine and slap the car in reverse.
