Looking for a simple and cheap tracking device for a car. Anyone ever use any and have any advice. Preferably OBD connected ones.

Take a look here.

Here is a unit that meets your OBD2 requirements. $50 to purchase and $10./month subscription. I would say, a thief would likely look at the OBD2 port right off the bat. But it might teach honest people a hard lesson.

Look at Rzrtracker.com.

CJ cannot be beat with customer support. He has gone over and above. I have it on two of my vehicles and have other racers who use him too.

He is in Oklahoma.

I had Linxup on my trailer for many years, like the above, very good. Just ran a wire from the small receiver on the roof to the winch battery.
I think of these every time I see a stolen trailer...

I use linxup as well, works awesome.
