no wheel alignment at PDI.. although they should have test drove it. car comes aligned from factory..
check tire pressures...check tire size.. dont assume that the pressures were checked.. also a wrong size tire from the factory isnt totally unbelievable.
wheel alignments are covered for the first 2000 miles as an adjustment so dont let them sell you one.
as for the rattle??? as for the 'loud start up" >>> most BMWs do start somewhat louder than you may want or think... i didnt listen to your audio clip so im only going by experience.
