Sorry to disappoint you but that's a serious, if small, collection and it's not the kind of thing the bank just gives you unsecured loans on. Unless he's borrowing straight capital against a successful business, I dunno where he'd even get loans like that. Additionally, none of those Ferraris are depreciating, although the Bentley could be. I have no clue who this guy is, he's 10 thousand miles away from me, but he's obviously wealthy enough. The level where toys don't imply personal debt is actually pretty low... a boomer with a $100k RV or a $200k boat is likely to be in debt for it, but the guy with a few million dollars in showcar probably isn't.
That F40 (super sick car btw) is a concours winner and it would easily liquidate for a cool million. How much it could get at auction is up for debate, but if it's got all the right papers and an interested buyer, 2 million+ is entirely possible. The market has lost it's mind, basic bitch factory MKIV Supras are now investment purchases, shitty old whaletail Porsches get $50 grand.
That 458 SP is fucking sick too. With the exception of the Bentley, that is a tasteful collection. Absolutely shameful if he doesn't track at least one of them, missing out on tracking a hypersport Ferrari would be unforgiveable. It's just money bro! Also he needs to buy some good lighting because the garage LEDs (?) are raping the fuck out of the color hue, especially the reds.
