Need a car Rental till I find a new car. but insurance won't provide me one?

There's nothing to fight, so don't bother.

You're entitled to a rental until your vehicle is fixed OR until you're offered a total loss settlement, and then the insurance company stops paying for the rental. Your vehicle is a total loss, so you're entitled to a rental until a settlement offer is presented. Here's why you're not covered for a rental anymore....

The cost of fixing your vehicle is more than __% of the total value in fixed / pre-accident condition (the percent number varies by jurisdiction), so your vehicle is written off. That doesn't mean your vehicle can't be fixed, it just means it's not financially worth fixing. Doesn't matter if it still drives, doesn't matter if the damage is all purely cosmetic, doesn't matter anything else. The only thing that matters is that it's not worth repairing. And your vehicle is not worth repairing. It's a fact.

You're not covered for a rental after a total loss settlement is offered for two reasons. The first reason is because you'll think the initial settlement offer is way too low, because everyone always thinks that. A vehicle is always worth more to its owner than it will ever be to anyone else, no exceptions. The insurance company looked up your vehicle's value with more than one source, and the amount they offered you is fair according to any court of law, but you still won't be happy with the amount. They know that, which is why they won't cover a rental until you receive a better offer. They'd be paying for your rental for months or years before that happens.

The second reason is the fact (and it is a fact) that you want to find a suitable replacement vehicle. Sure there are lots of vehicles on the market right now, but you need (just for example) something with all-wheel drive AND third row seating AND fabric seats AND under 100,000 km. Because that's what you were driving when the accident happened, so that's what you're entitled to replace. But it could take months or years to find that, and rental companies charge by the day. If the insurance company agreed to wait until you found the perfect used vehicle, they'd end up paying millions in rental fees. And they're not going to do that.

Auto insurance isn't a public service, it's a money-making business. In business, spending millions to make hundreds is just a bad idea all around.

You don't have a leg to stand on. After you get this terrible dilemma solved, I suggest you learn how to construct a paragraph using proper terms spelled correctly.

Grammar matters

If the car's a total loss, then you're going to need to get another one anyway, so just do it now. You know that you can't keep the rental forever.

You might be able to get them to let you keep the rental for two days, but that's about the most that they can allow. Once they realize that it is a total loss and they can pay what they are supposed to pay for a total loss, they can't keep paying for a rental.

The 30 days is allowed only if the car is not a total loss and is being repaired.

If you need more than two days to find a new car, then you have to pay for the rental yourself; they aren't allowed to.

You settled it's a done deal now.

Your fight should include compensation for loss of use of your vehicle. Once you settle, all you get is what they offer you. What else did you lose? How about the set of new tires you just put on? New battery?.....no such? Ask them what settlement they're offering for your total loss. Would you like to keep the car, value minus salvage, and fix it up yourself?

Ask your own insurance agent to go after them for more IF you deserve more. You pay insurance for protection, so get it.

If your car was driveable, see if they will let you buy the totaled car back (should only be a few hundred bucks) - you will have to get a 'salvage title' for it.

you might have to pay for it on your own

OK. So they gave you a thirty day rental with the expectation that your car would be repaired in that time frame. Now they just decided it's totaled and want the rental returned immediately.

Check to see if an attorney will take your case for free. You can't legally drive your old car with a destroyed bumper in many states. And it's going to take you at least a week to buy a replacement vehicle.

There are used cars everywhere, you can buy one today, you have the money, so what's stopping you?

The insurance company is not required to, nor will they, provide you a rental car for an indefinite period of time while you shop around.

30 days is plenty of time to find a new car
