How reliable is a Suzuki Aerio or SX4?
I don’t have an SX4, but I have a 2006 Swift 1.5GLX (this is a European model – not sure where you are in the world). In extremely happy with it. In terms of mechanics, it has been totally reliable so far. The only glitch has been a problem with the electric window mechanism on the drivers door, but this was fixed in a matter of hours under warranty (in the UK, the warranty is 3 years as standard, along with Suzuki Assistance recovery). Servicing is no more expensive than any similar sized small cars I’ve driven (I previously had a Fiat Punto which had similar servicing costs). Where there is a eal saving is the cost of the car itself. My Swift is a 1.5l engine, keyless ignition / entry etc, alloys, front fogs, and was under £9,000 new. Similar spec for a Toyota or Ford, for example, would probably be closer to £12,000+. Hope this helps somewhat.
