The rule proves the rule. Exceptions neither prove, nor disprove it. They are exceptions. Outliers. If you really wanted to average ALL Audi models US/Euro pricing you would find an average of about 0.93 (I did it... And most of ours have MUCH more standard equipment too).
The R will not cost any less (as it doesn't in Europe as it is) and it will not weigh more (as they are virtually the same car) but the S3 could be Sedan only with Golf R hatch only (of course).
the rule doesn't prove the rule. the majority of data points following the rule proves the rule. exceptions work toward disproving the rule. a single exception is an outlier. many exceptions together are more than just outliers, and may even become the rule.
we can at least agree to that.
