How many vehicles is too many?
On a similar note:
A few short years ago I found myself owning 3 cars and a motorcycle.
I live alone, which is how I managed to keep the motorcycle in my living room
I had 2 Corvettes sitting covered in the garage which were my toys which I barely drove, plus a daily driver in the driveway.
I became ill about 2 years ago, and decided to sell my daily driver (G35) and drive one of my Vettes which was brand new(and was depreciating even though I wasn't driving it).
I also sold the motorcycle. Now I'm down to 2 Vettes.
My illness caused me to have a problem shifting, and I became a danger not only to myself, but other drivers.
Well, I made a tough decision to sell that car and buy a car with an automatic tranny, which I did.
I was now sorry I sold my Infiniti.
I still have the one Vette, but now I'm able to keep both cars in the garage.
The good part is my arm/hand have improved, and am able to drive my Vette occasionally, which is a 6 speed.
The bad part is, about 6 months ago I began collecting Smith's

It was pretty hard to keep the buying under control, but I've managed not to buy a gun for about the past 3 months. It certainly is a challenge to my willpower.
I'm also a senior citizen, and don't want to end up leaving a collection of guns for my estate to dispose of (and them not having a clue to their value).
