it seems not really an MP3 problem but a media problem... Car players are often quite picky about media. I suggest you to try with good quality CD-Rs, like Taiyo Yuden, Verbatim... A search through the forum can also help you, this is a very well known and discussed topic.

I use nero and burn mp3 cd's by dragging files onto the screen in iso mode. i put them in different folders and all seems to work perfect in my mp3 car stereo, but the same cd's skip and make annoying glitch sounds when i play them in my friends mp3 car stereo. why is this, Is there a special way that im supposed to be making mp3 cds?
