i didn't go with TD because they required an alarm system be installed,
and they will not allow you to install it. they request is be installed by a specialist with documentation proving as such.
i have also been told by other riders with TD who weren't requested to install an alarm. i don't get it.
however, with that in mind, and if you're willing to spend the money on alarm and install, the rate was lower than other places.
still i went with statefarm, as i didn't wan to install alarm. got a better rate bundle with home and auto.
