What you're describing is called a "voluntary repossession," and yes, it's still a repo. The advantage is that you avoid the repo fees ($350 is about average), because the lienholder doesn't have to hire someone to go out and take the car. But it will still show up on your credit.
You may, depending on how much you owe on the car and how much it's worth, do better by selling it. If you sell it, then you can use the proceeds (and possibly some of your own money) to pay off the loan, and your credit report will just reflect that the loan was paid off (in general, this is a good thing). This probably won't be an option if you owe a lot more on the car than what it's worth, though.
As long as you are in default, they can repo. Try to catch up the month behind. Send $5.00-10.00, whatever.
Yes, they can. Consistent communication is the car-key to your vehicular retention.
if you are behind on payments then yes they can
two
Heck NO. LOL they might want you to THINK that...
ONE day.
3 payments
The repo man will tell you that, but no it is not true.
Not as long as the payments are current and have remained so.
ABSOLUTELY
If "you" are the lienholder then yes. If you're not the lienholder or their authorized agent (e.g. a repo man working for them), then no.
Legally, ONE day. As long as you are in DEFAULT of your contract, the lender CAN repo the collateral. Read the contract for more on DEFAULT.
