Depends on you man...YES, the Lexus is more reliable...It is..Not much, but it is...But its not a BMW..Its a passion for most..(like me)...
Having know all the reliablility issues, go to your Lexus dealer, sit and drive in the car, and then go to the BMW dealer, and do the same thing..If you dont know right away whcih one you want, get the Lexus...
