You know, I would say that I was exaggerating a little to make the point, but that's simply not true here: I've literally counseled folks who're locked into $400/$500/mo. fancy insurance as part of their car deal. Sure, you can get it cheaper in some cases. In others, you can't. Much depends on location as well: rates of uninsured drivers and the like. And $400/mo. = $4,800/year = real money. They can't do much about it because their contracts required specific fancy policies, which they didn't bother to check before financing.
No doubt if you have a horrific driving record and/or go buy a $200,000 Maserati sports car or some thing (where you clearly don't give a damn about being frugal in the first place) you will get that kind of rate.
But there's no chance in hell someone with a good driving record buying a normal practical car is going to pay $4-500 a month for just comp+collision.
For fun I just did a quote if you were to buy a few different brand new cars with the following parameters:
* Single (more expensive)
* Just 1 car insured (no bundling discounts of any kind)
* Clean driving record
* always picking the most expensive variant of the vehicle
* $500 deductible
Make: Yearly comp+collision
Subaru Outback: $460/
yearF F-150: $482/
yearT Camry: $522/
yearBMW X3: $672/
yearMaserati Ghibli (for giggles): $948/
yearWe've financed several cars and none of the creditors we've used required a $500 deductible. Most insurers will offer at least a $2000 deductible which can cut 50% or more off that yearly cost.
We don't have a brand new car, but it's a late model and an expensive one and my personal comp+collision is $190/year (though I have multi-line discounts and a other discounts as well as a $2,000 deductible.
