Well, if you’re looking for a fuel-efficient car, then a Honda Jazz is a very good choice. With an official combined fuel-consumption figure as low as 5.7 litres per 100km, and the ability to run on the cheaper 91-RON unleaded, the Jazz’s weekly fuel costs will be among the lowest around.
But $15,000 is a crazy figure. The entry-level Jazz was only about $16,000 when brand-new, so even though the kilometres showing on this one are extremely low, the price being asked is astronomical. The most expensive 2008 Jazzes out there are asking around $8000 (and that’s too much) with plenty out there for $4000 or less.
The difference would be if you meant to type 2018 instead of 2008 (which is a better match with the odometer reading you’re quoting) at which point $15,000 starts to look like roughly the right price to be paying. Either way, the Jazz is nicely built, drives well and will be very economical.
