Good point on the radio. my brother'* was locked by the previous owner, so, when ever he'd disconnect the battery, he had to go to the dealer to have the radio unlocked. I forget if it was 35, or 45 bucks, but the worst part is, they never clear the code...they just unlock the radio. So, he had to pay every time. He soon got sick of that, and took the radio out and bought a Kenwood, or something.
This will happen if you forget your own code, or, if the previous owner forgot their code, and therefore can't help you out either.
I think this is a crappy policy. Maybe some dealers would do it for free the next time, but this local dealer.....like many...... are in it to make money..
