It can’t be very hard, I have seen more than a dozen salvage vehicles come through the shop for airbag recalls, liability insurance is mandatory in Nevada.
You want roadside assistance on a budget, rebuilt car? That is like expecting room service at Motel 6.
Where are you getting that . If the vehicle has a rebuilt title most carriers will sell Liability insurance but you may not get Collision and Comprehensive .
Triple A will sell their roadside service contract if the salvage vehicle has been inspected and deemed suitible for public road use. Of course every state has it’s own requirments.
When I crashed my 2017 Mini Cooper into a guard rail I had the car towed to the nearest mini dealership who arrange to have the accident inspection and the cost came up to around $8000
Since Mini is owned by BMW and it was a lease. I reread my lease contract and in the fine print it said car repairs were to be performed at a BMW factory authorized repair facility.
So I followed up and turns out the Mini dealership referred me a not factory authorized/certified collision repair facility. I live in Southern California and there aren’t that many surprisingly even in this area.
So I have the insurance company flatbed the car over to an authorized facility all the way across town.
They checked it again. A few days later they came back with a repair estimate that was now nearly $18,000 !!
That instantly put me over the loss total threshold and got me out of the lease.
There are shops that specialize in selling totaled vehicles. A vehicle totaled due to hail damage can be a great bargain. There was a thread about a tail light replacement costing $4000. We’re heading for a future where any damage to a car results in it being totaled. Never heard of “hard to insure” a salvage car.
Just because you have never heard of it does not make that common across all insurers. Most will give liability policies but may not give full coverage or require an inspection of the vehicle .
