Senior citizen who likes performance and have been more than pleases with my Mazda5. Traded a 2008 Mazdaspeed3 (a great car) due to a requirement for more space. Mazda5 provides adequate (much better than expected after the speed3) acceleration, handles better than many small cars, provides good mileage. MPG has averaged low of 25 and high of 31.6 and provides the extra space that was needed. Will normally only carry four passengers so rear seat not a problem although my teenage grandson has no problem setting there. No problems since purchase.
Style, gas mileage, sliding side doors and handling.
A speed3 type engine would be nice but not necessary.
