Sold my 97 "M" to get the Box. Had the Miata for 5 years. Only maintenance other than oil/rubber was an elec. window motor went out, and a new set of spark plug wires. Perfectly neutral on Hankooks, loved the handling. Complaints - not enough leg room for tall guys, needed a few more HP. 2006's have solved the legroom, not sure about power. FOT with the Boxster is more fun...
