Frequently asked questions

Does every state give a road tax credit for trade-ins?+

No — this varies by state RTO rules, and some states tax the full purchase price regardless of trade-in. Check your state's specific rule before assuming a credit applies.

Should I include dealer fees and add-ons in the vehicle price?+

For an accurate payment estimate, yes — add handling charges, extended warranties, or any other rolled-in costs to the vehicle price field, since they increase what you're actually financing.

Is a longer loan term always cheaper per month?+

Yes, but at the cost of more total interest paid and a higher risk of owing more than the car is worth (being 'underwater') for longer — compare the total interest figure, not just the monthly payment, before choosing a longer term.
