I was going to buy one and the guys at Napa told me that it's better to lose
some gas than to have someone punch a hole in your gas tank, They said 3
customers had that happen in the last 2 weeks.

As nospam pointed out, during the crunch of the 70s, I had to do
investigations on so many cars with punctures tanks it was insane. All
it took was an ice pick. Once they had as much as they wanted, the
remained was left to pour onto the ground.

That said, if your car is garaged and you are only out and about in
the daytime to places like the grocery, I'd go ahead and put a locking
cap on. The vast majority of thefts occured at night and to cars left
out. If you are at the grocery, etc, during the day, it's very
unlikely that someone will be crawing under the car and punching a
hole to steal gas, or to siphon gas.

As for which to get, you should be able to find one which matches the
stock cap.
