I got my 8 July 18th 2003, and it's made driving great ever since then. I averaged over 100 miles a day the first week, and drove almost 2000 miles the first month. This is a marked change from my previous driving habits. I owned my previous car (the civic) for four years and only put 27,000 miles it (that is less than 600 miles per month).
