If I had say $2.5 MM in net equity, I'd be open to taking out say 150k (about 5% of your net equity) to pay for something like this:

If the car is for ''business use'' then that would be ideal, and I would pay interest only, claim depreciation, GST, and never pay the loan back... kind of write off the equity as a cost of a lifestyle purchase.
It could be CF +ve for the first couple of years done this way.
If it's not for business use then it would be more expensive to hold (as it's non-deductible debt), and you should consider repaying the loan.
A ''debt recycling'' strategy that capitalises deductible expenses and interest costs and channels spare cash flow to reducing such non-deductible debt may be beneficial here.
Alternatively, you could pay cash for it, or lease it using surplus +ve cash flow from your passive investments.
Or, you could do what I initially said, and, pay the interest costs using surplus +ve cash flow from your investments.
Personally, I'm not that interested in cars, but it seems to pull the ladies, so I'm re-considering.
Thing big, and be smart about it, and it may not be that silly or impossible a purchase.
