I don't know what a good number of vehicles is, but I do know I don't like how insurance is set up in the US. Each of my trucks costs basically the same to insure, but I can only drive one at a time, and it's liability only because they are old and low value. When I added my third vehicle it was a straight up 50% increase. Insuring as a pleasure vehicle does almost nothing. It's probably time to shop around again, I just hate having to do that.

Other than that, I like having multiple vehicles.

Having a spare car is always nice, especially one that can be considered a beater.
OTOH, we are now empty nesters and have been for some years.
Simplification is always nice.
Why do I need to allocate parking room to an extended length E350 that gets used only now and then when I can rent a pickup or cargo van from U-Haul for twenty bucks a day for those occasions when I really need a hauler?
I'm thinking I'm going to dispose of it as well as an old Subaru and my BMW and just keep the newer Accord and Forester for my wife and my use.
Of course, that would then open the door for a new fun third car at some point.

I park it on the drive when snow is forecast as a Grand Marquis leaves a big spot that I don’t have to shovel.

I have three for two adults. See Signature below. Works out great when one is in need of repair / service.

Always been a two car household. But occasionally I think I need a small truck in the mix. Contemplating adding a Suzuki Equator, or used Nissan Frontier to my driveway. Could be useful now and then.

Mine are all paid off.

2 each 1-Ton Duallies
A Cobra Mustang
A 1993 Ranger with a hot V8 in it
A 2008 F150 with 190,000 miles
A BIG ol' 60-series Chevy truck (weighs 14,000+ lbs empty!)
A Harley Softail..... a Ninja 650...... etc etc

I thought a lot of people up north had a 3rd vehicle as a "winter" vehicle?

One of the very rare times I’ve agreed with Triple Seven. I had three cars for this exact reason, and unfortunately was persuaded to sell my Forester. While it wasn’t anything fancy as the third vehicle, it always started stopped and made it to where I wanted to go without fuss. Now down to two vehicles, when there are repairs I cannot handle in the driveway, I make my wife arrange her own work transportation since this is her fault!

This will be remedied upon our next vehicle purchase, as I am keeping both Subies and adding a third.

Since every vehicle I’ve owned in the past 8 years has been bought free and clear, I see no reason to offload a known, reliable vehicle that may take $250-500 per year in preventive and corrective maintenance and take on a new vehicle with $400-600/mo payments PLUS preventive maintenance. I’ve conquered the “me too” syndrome of financial indebtedness by not wanting the latest and greatest vehicles.

My wife and I have 3 vehicles. I store my nice car during the winter (Minnesota winters are horrible on cars) and drive a 05 accord during the winter. During the summer we use the accord as a care free beater.

The 3 vehicles in my sig plus two tractors an atv. Bought a 75 GMC with grannie gear 4 speed minus engine for 500 bucks for a project. Have a 327 365hp to install then determine if we will clean up for resale. If it doesn`t sell will use as a woods beater to haul fire wood.

I’ve got 3 but I let my brother drive the Camry.

The Sonata does almost all the miles, the Jeep gets driven occasionally. It lives in the garage. Either my garage or at the mechanic’s

3. That is why I got Toyota Sienna, so I can get myself next year BMW 335i or Audi S4 for pretty much anything, unless long trip with family.
There is no freaking way I would drive Toyota as only option every day.
As for ownership cost it is either:
3 vehicles with one of them being fun car for me.
OR
2 vehicles, one of them being super fun SUV that can meet family needs, but then maintenance costs would probably equal Sienna + fun car and still SUV is not fun as stick shift sporty car.
OR
Just VW Tiguan + Toyota Sienna+ paying shrink due to consequences of being stuck driving Toyota.

I have 7

I am 38 and single.
I now use my Ninja to commute in the city and work and the suburbs.
It was my only motorcycle from 2009 until 2014 and have been used from long journeys to track days until that time.
2014 was the year to purchase the CBR - for a fun/trip bike.No city use for that (too heavy,not very comfortable riding position high consumption,overheating in summer) exept from special occations (e.g. The Ninja is at the repair shop)
And my old trusty Ford Fiesta (model 2005) mainly for the errands and big trip to the parents (1500kms to go and return) or journeys on rainy days - passengers etc.
So 1 car and 2 motorcycles for me serves me absolutely fine.

Depends. Most people I know don't, they seem to opt for a new AWD whatever every few years. Road salt means only DIY types bother with old vehicles--at some point it seems too expensive to keep a car too long, at least if you have pay others to do all the work.
