I´ve drove mine for about 45 miles one way. Probably about 150 the most I´ve driven it in one day. It runs like new. Mine is only 3 months old with 1200 miles. I too, want to juice it up a little. I´m wanting to put an iridium plug and matching coil, and perhaps a performance air filter if available. I´ll let you guys know how well it does after the modification...
