The Swift is a good replacement for your Alto. Modern diesels, like the Swift multijet, are reliable and much more economical than the petrol cars. You need to opt for a diesel only if you do a lot of driving (more than 40-50 km a day). But in your case, the petrol version of the Swift should suit you very well. Since you want a spacious car, you might also want to look at the new Hyundai Getz Prime (read story above) which we believe will be competitively priced and a good bargain as well,
