I (31/m) pay $2000 every six months for $300k/$1 mil coverage on my spyder with Allstate and no mileage restrictions; I've got a ticket for 64 in a 45 and one for no seatbelt over the past two years. All of the specialty insurers were more, or much more, and had mileage restrictions and other dumb restrictions like no coverage if it isn't garaged at my house, etc.

Maintenance is mostly zero so far, got it last October at 69 miles and now have 3200 on it and have only had to put two liters of oil in. I'll be taking it in for the annual check/fluids in a month or two and expect that to cost about $450.

My car has seen some track time at Sebring which has put heavy wear on my front left tire, and with asymmetrical tires that means once it is gone, all four have to be replaced, so I'm anticipating needing new tires in about 1000 miles which of course won't be cheap.

Not sure on financing but that won't be specific to Lambo, just whatever you get on the loan.
