Yes I've posted about this. Name changed as I don't want the tribute thread to be too linked to this. I have fuller facts this time.
My brother had two cars. Both of which he insured my dad to drive on. One (the more expensive/luxiorious/automatic), he signed over to my dad, but it was still his car. My dad had a 'cheaper' make of this model. Then my mum & dad got another car and gave my sister their cheaper model (she was supposed to pay, but never has as she's always short of money.)
Eventually mum & dad ended up using DB's cheaper car. No one used his expensive one - as it was expensive.
Then during lockdown, my sister and her new boyfriend (she met him just before lockdown, and he moved in 6 weeks into lockdown) needed a larger car to collect something. Dad lent them DB's nice car (for one trip only).
Then DB became ill, so they kept the car to take mum and dad to hospital (Dsis's car was big enough!). Dsis refused me a lift when I was told to see him, as my daughter had seen a friend, and she didn't want her in the car as Dsis's new partner's blood group is A. So I told her that we would need DB's car the next day, as our car is too small for DH to drive mum, dad, DD, me and him in (tiny car). She went mad. Her partner went mad. Her partner refused to have anything to do with me, even though he'd never met me. All because I said we'd need to use a car that didn't belong to them, and they'd borrowed for ONE DAY!!!!
My brother died, my mum wants the car back and she and dad have fought like mad.
My dad has terminal cancer, osteoarthritis of the spine and hip and is 75. He is having to drive a manual car that is too low, even though the car that DB signed over to him (and dad is actually the registered keeper of) is an automatic, higher up and was easier for dad to drive.
I found out that the reason that Dsis is using this instead of the car dad 'gifted' her, is she hasn't paid the tax and insurance on her car.
Here's the killer though - she has turned up this week in her other car! So she has a third (second) car that is tax and insured.
So the only reason mum and I can see that she hasn't returned dad/db's car, is that her partner is driving it, and he has NO intention of returning it (she has agreed to, she was supposed to bring it back yesterday, but came over in her little car).
I know her partner sold his car when he moved in with her, and doesn't work (and my dad pays for their petrol).
My mum is very distressed, even she could drive an automatic.
