My friend is moving to Tokyo and is willing to sell me either one of his two cars. The first is a 2004 Toyota Prius with 41K miles. The cars is clean, with a few bumper marks from city driving. The second is a 2006 Mazda 5 with 9K miles on it. The cars are each available at the same price, and I'm wondering which vehicle is a better buy. My wife and I are unversity town folk and don't expect kids for another seven years. We drive about 12K a year, although that number declined since we moved to where we are now. Any advice would be greatly appreciated!
