First are you recording MP3's to CD-R Wav format or does your car stereo support MP3 format Taha?
If you are Transcoding from MP3 format to a WAV-CD then that is never good for quality. The CD-R's themselves are a non factor, they only record the signal being fed to them, wouldn't make any difference if it's Maxell, Verbatim or any other manufacturer.
I have about 50 coasters I have burned which just didn't sound right, I keep a few around just to remind me to always do a practice burn on a CD-RW before a permanent copy. And I never transcode anymore,,,if it's a FLAC to WAV format then it gets a CD-R burn,(FLAC & WAV are both Lossless formats) if it's MP3 then it goes to DVD archive storage, and I simply load the albums/songs on my Sansa when I want to change my library.
