Funny, I’ve asked this exact question multiple times, and the answer I always get is that you just get fucked. You pay full price for the first vehicle, and then 90% of full price for every extra one.

Maybe it’s Georgia? I carry the minimum for the state (Liability + Collision), but then bump the Liability because I now live in a high cost of living area. So if I’m in a wreck, I get nothing, but the other guy gets a nice check for his car and his medical bills are covered.

My car insurance would be WAY cheaper for me to just drive one of my shitboxes 100% of the time than it is to split my mileage across four vehicles. But I make it up by being pretty handy. When one of them breaks, I have multiple other cars to drive while I wait for parts in the mail. So I’d still say I come out slightly ahead as far as costs go, but most of my ‘savings’ go straight to the insurance company.

Yeah you get fairly large discounts on extra vehicles, the logic being that you’re only driving one at a time and so collision and liability coverage costs only go up a little for each extra vehicle.

Each car needs a separate policy, but if you get all your policies through one company they are likely to throw a discount at you for multiple cars. OTOH, it also means if you get in an accident or get a pile of tickets your rates will probably go up on all of them. And, of course, you probably don’t need collision on a shitbox car that’s paid off.

It may also make a difference what you use them for. They may give you a lower rate if they know it is not used daily. I know someone with an old 60’s-era Mustang, he has it on a special policy that is much cheaper because it’s for classic cars only. But there is a limit to how much he can drive it in a year before his rates go up. It’s basically for old cars that you only drive to car shows or just to show off, and keep off the road entirely in the winter.

‘shitboxes’ often don’t have comprehensive or collision coverage, just liability–the cost of which is mostly based on who is driving, not what.

Others mentioned multi car discounts, but you can also suspend coverage on a vehicle and restart, or have a low mileage policy that restricts the amount and type of driving. Different carriers will offer different options.

Edit: and old inexpensive vehicles driven infrequently are often relatively cheap to insure.

Old cars are much less. A good driving record makes a big difference. I fear the day when my kids are old enough to drive.

It’s about $80/month each for me. I’ll usually keep two deactivated while they are parked in the barn. I’ll have two active, and the other two are either waiting for me to repair them, or waiting till the other two break down. Sucked that one time I had three down at the same time…

Liability only is dramatically cheaper, and older vehicles cost less. My motorcycle is $90 a year, whereas my Model 3 and my wife’s CX-5 is $3600 a year combined.

Older cars have lower rates. You can drive a fifteen year old POS and get full coverage for $20.

You can get a quote to add an additional vehicle before buying it. I suggest you do that.

It costs me $450/month for 3. That’s with discounts for multi policy, adult drivers, anti-theft, anti-lock brakes, and airbags.
