For yuks, i ran a Carfax check on my 85 Golf GTi, and they reported that it had it's emissions tested in Lancaster, California several times (which is completely untrue), and that it had failed a few smog tests which is also completely untrue. I've owned it since new and it has never even come close to failing a smog test and always passes with flying colors. I wrote them for an explanation and they replied that i must be mistaken. On my 89 325is, there are two smog tests that are not on their report despite the fact that the car has been tested every two years since it was new (and i have the reciepts from the previous owner). I wrote them about it and this time they said sometimes things don't get reported. Needless to say i don't have a lot of confidence in their ability to accurately report a car's history. FWIW.
