do you have an explanation of how you managed to purchase a vehicle that was worth $27K for$15K? just want to make sure you haven't omitted something important. if not your basis is the $15K paid + taxes. licensing would only be included if it was a one-time fee but most licensing is annual
barring any missing info you sold the old vehicle to the insurance company for $27K so you now have about $12K taxable gain. your basis in the replacement vehicle is what you paid.
