As long as your car has less than 100,000 miles and less than 10-years-old, your lender should allow you to take out a loan to buy a motorcycle. Just remember that if you default on your loan, the bank will take possession of your car.
Keep in mind that because the car acts as collateral, you’re going to have to get full coverage auto insurance until you pay the loan off. However, you can save money with a multi-vehicle discount, so make sure to inquire about it while you’re shopping around for insurance.
