The 2009 Daihatsu Sirion is a clever city car offering excellent interior space, frugal engines, and solid standard features. It’s reliable, practical, and well-suited to urban life—especially in manual form. Go for the 1.3 L or sporty 1.5 L manual if you prefer a peppier drive. Stick with a manual gearbox and check for cabin noise and seat fit, especially if you’re taller.
