Don't want to share my car!

[McScrooge]

Been sharing my current car with my sister for a while now. It worked out well as she'd do longer distant drives for me that I couldn't do at the time and that was the agreement in turn for her using my car.

All was grand, until she started getting a bit big for her boots and expecting the car to be there everyday when she wanted it, and would kick off when I was using my car and wouldn't be at home.
She no longer does any long distance driving for me either and hasn't for about a year now mainly because I'm forcing myself to do the drives to build my confidence.

I'm getting a new car next week and she's kicked off that I haven't already stuck her on the insurance, I can't put her on the insurance until it's live and gone through on the day and didn't like the fact I told her I wanted a few days to get used to my new car by myself.

AIBU to think if she's kicking off already then I'm best not sticking her on the insurance at all?
It'll cause world war 3 but all she does is pay for petrol, she doesn't pay for anything else like MOTS, upkeep etc and drives it more than me!
I appreciate all the driving she has done for me in the past but I really just want the car for myself now and not have to worry about having to get home to avoid a kick off or have a stupid rota for using my own car or do I sound like a Scrooge?

Can you gift her your old car? Since she likes using it so much.

Will she even pay for the increase in your insurance premiums?
I would just say no now. Sometimes adults need to have their own car and particularly if she is giving you a hard time over it, just say no.

Very odd. No, if she’s demanding your car is available to her daily, there’s no point you even having one! Cheeky mare. Don’t put her on your insurance and tell her to get her own car.

"Why haven't you put me on the insurance?"
"Because it's not your car"

Any driving favours she had done you have long been cancelled out by free use of a car saving her £100s a month!

“Sorry this arrangement doesn’t work for me anymore”

Declare that you now do your own long distant driving and you'll be keeping the new car to yourself.

Ask whether she'd like to buy your old car from the dealer as she knows and likes the car. It is an opportunity for her.

Why do the rest of your family enable her?

Ask her to pay half the cost of buying the car and the ongoing costs and see what she says.

No idea, one of my siblings is no contact with her. I'm thinking this may be the way I need to go if this continues!

I'll update when I have an update.

Don’t bother with all these suggested excuses – she will find a way around them.

Just say – No, it’s my new car & I don’t want to loan it out. You could make the odd exception, but it needs to be the exception that she uses it rather than the rule. At the moment it’s a given that she can use it whenever she wants, at your detriment, so that needs to change.

Owning and running a car is an BIG expense. So much so that when older people give up their cars, they find that the cost of taxis for the 1-2 times a week they need it costs them less than keeping a car going.

One of the things you are buying when you own a car is access to it whenever you need it. Seems to me she has had the access without the payment. Hardly fair.

Just send her a text saying that that arrangement is no longer working for you. Let her kick off. You aren't doing anything wrong!

Update;

She's just been round, asked me what I'm doing tomorrow for my birthday.
Said I'm going out in the afternoon, "well I hope you have a nice time in the morning, make a day of it you don't want to have to rush out after lunch then be back by 2 and then have to rush to cook dinner."
"I said I'm going out after lunch in the afternoon."
"Well you don't want to have to rush back a hour and a half isn't much of a day."

UGHHHH literally nearly blew my lid. She's not going on the new insurance for sure.

Tell your family 'fab, thanks for offering. I'll let her know you're sharing your car with her from now on'

Have the row, tell her to piss off.

And make sure you present her with the bill for half the costs of the insurance, tax, service, Mot, repairs, etc. Then point out that if she can pay all that she can pay it for her own car. What a fucking child she is. Does she hold down a job?

No she doesn't have a job. Says it all really!

Very tempted to send her a text now saying I'm using the car tomorrow and for the foreseeable future (which is true I need it for the next 2 weeks on a daily basis!)

"At the moment you're using my car now than I am, and when I need it it's not available. The new car is costing me a lot of money, so I'm not prepared to not be able to use it when I want to"

Name change fail op?

Plus I hope you are just going to go out in your car all day?

Can’t you offer to sell her your old car?

Good lord, your sister is the very epitome of entitled.

She's probably part exchanging it

What did you respond to that?

Something along the lines of - what the actual fuck are you talking about? I'm going out for my birthday in my car and I won't be rushing anywhere - I hope.

Please grow a back bone and do not share the new car with her. It is yours, you can drive anywhere you wish. It is not hers, at all. Stop enabling her entitlement. Just say no, this is my car. Buy your own car.
