Well, only the Lamborghini is a luxury car(unless you consider all cars a luxury but that would be a different discussion).
Otherwise, I fully agree with your point. I like cars and had no clue what, exactly, the Pontiac Fiero or the Chevy 350 were as I'm not American and those are American cars. Around here German(Mercedes, BMW, Audi, VW) and Japanese(Mazda, Subary, Toyota, ...) cars are much much more common.
Fiero: Pontiac's great experiment at making a European style sports car. A real _proper_ sports car: Mid-engined, rear wheel drive. Except, because most most of the parts were from other GM vehicles, it was mostly shite. Still - very popular with kit car/replicar builders because they made quite a few of them (~350,000) and they're cheap as donor cars.
Chevy 350: Basically a commodity engine. 5.7L pushrod V-8. Used in lots of GM vehicles from the late 60s through the early 90s. Camaros, Corvettes, Cadiallacs etc. Built tough, cheap, and there are a gazillion aftermarket parts available.
It's fairly unusual these days. Only thing you'll find with an engine that big is either a full-size SUV, a large truck, or a Corvette.
Plus, if you weren't here, you might not appreciate just how horrible the "EPA era" engines were. Much stricter emission controls + not having the technology to really meet it led to some really de-tuned engines. Wouldn't be unusual for a 5-6L engine in those days to only make 140-160HP stock.
