Had it not been the Ford Figo, I would simply recommend the Skoda Fabia because it offers exactly what you want – Spacious boot, decent mileage and comfortable interiors. It sure is a worthwhile alternative to Honda Jazz, which does not yet comes in Diesel. In fact, Skoda has also dropped their spare part costs which are now lesser or almost close to that of Jazz. As far as after sales is concerned, it still might be a cause of worry for some prospective buyers but is certain to improve ahead in future because of the seriousness with which Skoda is working towards Indian market. And I would also like to quote what Shailinder said elsewhere.
After Sale Support: hmmm. It is problematic but still things are improving (heard). If we can believe Fiat, I think we can also believe Skoda. (No offense intended for Fiat owners)
Note:- I have got following spare part list, they are not very expensive. Please do not compare with Maruti or Hyundai.
PS: You can find the list of Skoda Fabia spare parts cost in above quoted post.
