Converting MP3s

My wife loves to listion to books while driving . Awhile ago she found a series she loved and bought the CD at a great price. (now we know why) they are recorded as MP3s and her car CD doesn’t play MP3s.
Whats a good FREE program to convert them to a playable format? She drive a 2000 Toyota echo.

I can recommend

if her car does not support MP3 format, it probably doesn’t support DVD disks either. So you should buy some CDR and then simply burn a Audio CD from your MP3s. It will automatically convert format. Just remember a CDR is only 700MB so you can only fit a limited number of songs (typically 8-15 songs).
