...in the past 8 years. Our Lexus has 137,000+ miles on it, and gets about 14mph. That's almost 9,800 gallons of fuel (that sounds bad enough!), and I figure an average cost of $3/gallon (not sure what the average really would be between 2004 and now), that's $29,400 spent just on gas. Yikes. Of course this isn't a fuel efficient car at all, and wasn't cheap up front. But it boggles the mind that we've thrown almost $30k on this one car (we have a few others) at gas. (And I'm not calculating oil changes and other engine maintenance costs). Can't wait for my Model S.
