It's fun, it's something to do, but didn't seem very productive. I probably tried out 40 cars. Only 3 were unlocked. Here's the breakdown of what I got.

Car 1: Lots of CD's, but most scratched heavily, and out of cases, picked up 2 burns, Coldplay, and a GAP greatest hits CD (some good music on it); 12' small measure

Car 2: Chump change (c. 50 cents); lots of cassettes, didn't bother taking

Car 3: Small, low-quality flashlight; about $10 in quarters

Any critique on my strategies?

I went out at about 12:45; walked about two blocks and began trying every cars passenger side doors. When inside the unlocked cars, I acted like I owned them, and was just looking for something. I checked the armrest, dashboard areas, glove compartments, and back seats. Any way to improve? I also checked the backs of pick-ups, but only a lawn chair.

To increase profit, you need to get into more cars. Therefore, I reccomend investing in a slim jim. A slim jim is a item used to break into cars;

You can bye one from links on this page;

Also, to plan escape routes, use google earth;

And go at 3am-4am in the morning.

Yeap. Unless you break into cars, you're really not going to get much out of car shopping.

allright, so this brings about the question of how to break into cars. Do I somehow aquire some slim jims, and try to teach myself? The link above only really sent me to a $250 course.

Sorry, 1 min.

What's the deal with those ninja rocks in spark plugs? Anybody actually use them?

SWIM finds them very handy, a little 4x4 piece would work for a window. It spiderwebs the window or breaks it all the way. If a window has tint on it, the window will stay together. So you would have to smash it out with your fists.

I have gotten the same things you have got. tape measure, bag of quarters, several flashlights, and cd's.

ya well I now have a partner who has and knows how to use slim jims, so I'm thinking of some great stuff now. Like skis/snowboards in cars during winter, and maybe Christmas presents too.

Dude, don't do christmas presents, that might ruin a kids christmas.
That is just low.
