Average vehicle curb weight in 1979 was roughly 1,600 kg (3,500 lbs), for example, down roughly 225 kg (500 lbs) from four years earlier.
Not all cars went on a diet then, though. In spite of the trend, the '79 Cadillac Seville still measured in at a whopping 1,896 kg (4,180 lbs) — in other words, "heavy equipment."
It's terrific Tyrannosaurus paint job didn't justify buying last week's Jurassic Park Ford Explorer, according to 70 percent of readers. We assume its $6,499 price made its chances at the Worth It vote extinct.
The price tag on this week's candidate is about 10 times as hefty, but then again, so is the car.
It's a two-place Cadillac Seville Grandeur Opera Coupe the seller figured was large enough to warrant filing under "Heavy Equipment" on AutoTRADER.
We laughed at first, too — until we fully took in the car's aircraft carrier-sized hood. Oh, yeah. This is a piece of heavy equipment if I ever saw one.

The seller offers precious little information on the car, save the fact it's black-on-black and has 21,700 km (13,500 miles) on the odometer.
From what we gather, though, the Grandeur Opera Coupe edition Sevilles converted from Cadillacs back in the day were rare, numbering a few hundred units a year.
They were built on Seville sedan chassises with the front seats removed and the controls moved back to reach the rear-seat-turned-driver's-seat.
Hood and fender extensions – along with fake side-mounted spare wheel covers – completed the '30s-era opera coupe look.
Though the car was technically the same length and weight, the Grandeur Motor Car bodywork more than doubled the price tag back then. A $14,000 Seville outfitted with the conversion jumped up to $38,000.
That's equivalent to a $56,000 Caddy being transmogrified into a $140,000 custom today.
The seller's not asking nearly that much for it, though, instead slapping a low, low $59,000 figure on the thing. But is it still too high? You tell us.
