The part you all want to know: MPG.
I have observed, in the real world, 49.89 MPG on the highway, and this is not the XFi model with only 48hp. I have the "big boy" with the 55hp 1.0 3 cylinder engine. The gearbox (when maintained) shifts crisply (though the synchros are about shot, so you have to shift it by ear (not a big deal, no tach anyway). This car is very rewarding to drive, at only 1,600+lbs. It has no ABS, traction control, stability control, airbags, power steering, etc. This is a bare-bones little hatchback.
I curse the feds for making cars so bloated now where we cannot have such fun, bare bones little cars with personality. A damned shame.
It took all of this to get it there:
I got a very neglected car. The tires were low, balding, and needed replacing soon. The oil was black and was over a quart low. The spark plugs were caked white with carbon, but not oily (rings and compression were still good, thankfully). The transmission fluid was also black and low. I flushed both and now change the oil and filter every 1,000 miles. I ran SeaFoam in the gas tank, crankcase, and intake system. A little mechanical empathy goes a long way.
The starter started (ha!) clicking a few months ago, after a year of ownership, so I just replaced it, rather than have it go out at the wrong time. The starter I replaced was the original unit.
The automatic doorlocks (activated with speed) stopped activating a few months ago. The driver's exterior door handle is broken inside the door, I just have been too lazy to replace it. Eventually I will, when I get around to it. As it stands, I just open the passenger door and open the driver's door and then go to the other side of the car. Not Suzuki's fault, as little things do wear out, eventually.
I replaced the water pump (was the original unit, 16+ years of service), timing belt (also original!), valve cover gasket, cam gasket, crankshaft gasket, radiator (precautionary measure), hoses (original!), timing belt (original... did anyone maintain this poor little car before me?!), drive belts, spark plugs, ignition cap, spark plug wires, and the engine light was on when I got the car (replaced the EGR valve).
The guy I bought it from rebuilt the entire brake system, the CV boots up front, tie rods, and the entire suspension and bushings at all four corners. Apparently, changing the fluids was more work than rebuilding the entire brake and suspension systems! I hate it when people neglect cars! He bought it at the height of the gas crisis in 2008 for $3,000. I bought it for $1,300.
Finally, I added a new set of 12 inch Yokohama tires all around, and the car handles great. Sure, it's not a Toyota MR2, but for what it is, it is a lot of fun to drive!!! Get one, but don't get an automatic, not nearly as fun, or frugal on the gas!
All in all, a fantastic little car. If this thing was sold new today, I would buy it, as it offers the best mix of fuel economy, parts availability, handling, low insurance, and I think it looks pretty sharp, as well.
Pity Suzuki doesn't make these for the U.S. any longer. Why can't they get it together?! I want another Swift/Metro, Suzuki!!!
