First, make sure to lower the writing speed. I'd use x8 or something.
And some car stereos are more sensitive than others.

As for CLI rip/burn I just tried this (from the wodim manpage):
  "To copy an audio CD in the most accurate way, first run
    'icedax dev=/dev/cdrom -vall cddb=0 -B -Owav'
   and then run
    'wodim dev=/dev/cdrw -v -dao -useinfo -text  *.wav'
   This  will  try  to  copy track indices and to read CD-Text information
   from disk.  If there is no CD-Text information, icedax will try to  get
   the information from freedb.org instead"

You might need to adjust the device names to suite your setup.

I don't know (and I doubt it) if icedax is more accurate than  
cdparanoia but it seems to be the only "easy" way of ripping cd-text.  
I also haven't verified if it's really gapless but the -dao should  
indicate it.
