The Good and the Bad
 Shortly after purchasing it used at 59,200 miles, the coolant light came on so I filled it up when the engine was cold and it continues to leak whenever the coolant expands with a hot engine. I'm guessing the coolant expansion tank is cracked.  Other than the above mechanical issue this car draws a lot of semi-truck drivers attention and praises and other people on the road also.  It feels like this car has sticky glue on the tires during fast turns.  Manual 6-speed transmission shifts wonderfully.  Not the fastest car on the road against say a Ford 500GT or any other hot rods but this Z4 has the right balance between styling and performance.
