Readers: Two Sundays ago, I told the sad story of the disabled woman who was cheated horribly by a Long Island used car dealer.

Happily, there was also good news that touched a lot of people.

Pep Boys, the car parts and service chain, stepped in to repair for free nearly $6,000 worth of stuff that needed to be done to make the car safe.

And JP Morgan Chase replaced a usurious car loan to which the dealer had signed the woman with a fair one. Now there’s more good news: Chase decided to pay off the woman’s loan in its entirety — and then some.

Now it’s up to Suffolk County law enforcement to investigate the dealer so he can’t cheat anyone else.

Please read the email the woman’s social worker sent me:

Dear John: Happily, I would like to report that Chase bank last week told me that it will pay off the car loan plus the taxes due for this gift.

They have all been very gracious to me and I would especially like to thank Eric Shanks of Chase Direct Auto Finance in its Houston office for his patience and kindness.

In addition, I would like to thank the mechanics at Pep Boys’ Bayshore location for their work and for the extras, including brighter headlights and a functioning radio.

Nicole was our contact there and was always efficient and followed through orchestrating the details.

Special thanks to you for responding to my letter and for contacting the right people to make this miracle happen.

Best wishes for all your future advocacies on behalf of “wronged citizens.” Your efforts to make the world a better place are admirable. K.K.
