Haha, nice. The Quattroporte is one of the fastest depreciating vehicles you can buy. There are clean title ~15 year old ones for sale under $15k (~90% depreciation).
Curious - why do Ferraris hold their value relatively well but Maseratis don’t?
An excellent question. Some of it certainly comes down to brand name prestige. But also many more Maseratis have been built than Ferraris so there is a surplus of supply. The types of vehicles Ferrari builds are more niche which also increases their appeal. If you want a cutting edge sports car there aren't many choices and Ferrari is the most recognizable. If you want a luxury sports sedan or GT there are many competitors to Maserati (BMW, Mercedes, Audi, Jaguar, Aston Martin, Porsche, etc.).
Maserati also has a reputation for being unreliable and expensive to maintain. Ferraris are also expensive to maintain but presumably are more reliable (or people care more so they keep them in better shape). Another factor is Ferraris aren't driven as much so on average their prices won't depreciate as much due to use.
That's not to say though that Ferraris don't depreciate a lot either though. For example, if you look at a ~15 year old F430 with 30k miles or so they will have lost a similar amount in raw dollars as a Quattroporte from the same era, it just doesn't look as bad from a percentage standpoint ($200k->$100k).
Example (MSRP $219k -> $87k sale). And not
every Maserati has been a depreciation nightmare. If you were lucky (and wealthy) enough to be one of the 50 people to buy a
Maserati MC12 for $1.5 million in 2004/2005 you'd have seen appreciation instead of depreciation (worth $2-3 million today).
I'm mostly just making guesses here but I'm confident that the truth is mostly some factors of the above variables.
