They tend to shop around their deal to all of the other local investors when they use the internet.Not many calls from car magnets.

I also understand the concept of risk/reward and this actually is the most powerful "magnet" for REI for the rewards are significant if you are willing to do the work.

With 6000 pieces I spend $4680.Doing it myself, including magnets, costs about $3,000; without magnets it's about $2,000.

Most guys with pickups and magnetic signs don't have insurance, heck, they may not have a license!

Pick up the phone and start making some cold calls.Buy a magnetic sign for your car.

I never had my car wrapped - I used to have a magnetic sign on my car.

Magnetic stops, properly, and securely mounted, these last a very long time without damaging the door, including the fact they prevent doors from blowing shut when room pressure changes suddenly.I would be very curious to know how 3 sets of hinges need to be changed. not something that typically "wears out".

Charlotte is the biggest city and a very strong REI area but also a magnet for investors. 

@Gary Marcotte  You're sane.Have you put the magnetic signs on your car yet?

I have gotten several deals over the years from people calling me from my business card refrigerator magnet that I sent years earlier and now the owner or relatives are calling me.Jon has a really good point and is correct you do have to send tons of letters and the key is to be consistent.
