i don't have much experience. and i am now leasing an oddysey. when it reaches lease end, if i drove more than 36kmiles, or with some obvious damage, that dealer would definitely rob me based on that, i will buy probably, but if i drove like 26k miles. or way lower than the lease allowed, i will probably buy too.
i will only return, if you just put right miles on it and the car has not major damage. and the dealer could not charge me more.
but dealers will always try to oversmart you. so, becareful
