Never lease a Toyota through Toyota Financial Services. The customer service is terrible and completely unacceptable.
If you have to deal with TFS to correct a billing issue, it will take you several years and frustrating hours to get fixed, if ever. The customer service representatives will yell at you over the phone, not provide any helpful information and never follow up.
Additionally, any mail correspondence you receive from them will be late and unhelpful. When you call to question, they will blame it on the customer and not take any responsibility for their error.
Avoid yourself some frustration - do not lease a Toyota!!
