How Do Investors Acquire Cars?

I'm perplexed.  I need to acquire a car/SUV but since I've been investing, it seems that it is such a poor investment.  Given that most "good" investors do not throw money away, how do you acquire your transportation vehicle?  Purchase new or used for cash?  Finance new or used? Lease?  Borrow a friends?  Only take public transportation?  Bike only?  And give your best "investor reasoning" behind your decision.  Thanks.
