The 80-year-old Dunedin pensioner was left reeling on Saturday, after finding her Mazda 2 up on blocks outside her Middleton Rd home after thieves stole her wheels and tyres.
Her plight prompted a public outcry until Midway Motors managing director Chris Henderson stepped forward, offering her replacements worth about $350 free of charge.
He delivered on the promise yesterday, much to Mrs Isaacs' delight, but said he was just doing what was right.
``I believe in karma. What goes around comes around.
``We are a small community in Dunedin and I am in a position where I can help, so I did.''
Mrs Isaacs said the gesture was ``absolutely marvellous'' and restored her faith in people.
``There's still some good people around in the world, isn't there?''
Her neighbour, Mavis Pere, agreed, coming out on to the street to thank Mr Henderson when she saw him arrive yesterday.
``What a wonderful thing for you to do,'' she told him.
Police were still investigating the theft. Senior Sergeant Brian Benn told the Otago Daily Times information had been received from members of the public and was being followed up.
In the meantime, Mr Henderson said Mrs Isaacs would be ``good for a few Ks now''.
``And we've got a smile back on her face and taken care of some stress pretty quickly.''
