You haven't mentioned your budget, so it'll be difficult to recommend the right car. Since you've mentioned you want something as small as the Maruti Suzuki Baleno, the Hyundai Venue does make a lot of sense.
You could go for the 1.2L petrol version too, since your usage is going to be minimal. The lower variants are great value for money. If you want a bigger car for similar money, you could look at the Citroen Aircross X. However, your wife will need to get used to its larger dimensions.
