Is it legal to repo a car only 5 weeks from its purchase 500 cash down and a 1000 trade in allowance was paid and the first biweekly payment made?

Kay, were you in default of some other terms of the contract? INS,ect??? This sounds like a tote-a-note car lot and they normally do NOT allow you to get 2 days past due. IF you were not in default, CONTACT an attroney ASAP.
