My 1985 QPIII had a window sticker approaching $90,000 in 1985 dollars. The car was in perfect condition. I mean PERFECT with 50K miles. That included a machined finished exhaust option from Maserati of over $10K.
Factoring inflation, this was a $213,000 car.
I bought it in 1995 (10 years later) for $7,900.00, which factoring inflation is $13,246.00.
That's a $200,000 depreciation in 10 years.
Depreciation of Maseratis is nothing new and has been routinely characteristic of the marque.
The 1985 bodied car screamed outrageousness in its day and was the go-to car for every drug lord and mob boss and made appropriate appearances on Miami Vice. If there was a drug dealer moving millions in dope on that program, you can bet they'd show the goods stuffed into the trunk of a QP.
As a kid, I loved it. It's on-screen intrigue matched it's oddness on the road, with everyone pointing. 4 carburetors atop 4 cams, 8" stainless exhaust narrowing to 4 inch cannons a the tips, 6 shock absorbers, 5mpg with actual pulses of air that would hit your legs as you walked 10 feet behind the car, and a body so wide it simply WOULD NOT fit through the Barnett Bank drive through. It had to be the most inappropriate and impractical car ever made, but I loved it even more for that reason.
Maserati has gone through many downturns, while creating awesome, unconventional cars at the same time. But, with that lack of convention comes lack of demand and that is the reason why they rot standing still when placed on the used car lot.
