I've kept it for around 7-8 months as a daily driven vehicle. It is a nice reliable vehicle. Nowadays, you can get it in 12-15 lac range depending on the condition and options in it.
Difference between Alpha and Beta version is that Alpha version is more equipped.
Resale - these vehicles have no resale as these are not ordinary vehicles. Few buyers. Few sellers. But I sold mine for a profit of 2 lacs after using it for around 8 months.
Practicality- Only two adults can sit in it. Only Japanese versions have two seats in the back as well but one can't sit in them. Body parts are expensive as they are not common. Mechanical parts are easily available in the market.
Performance- It's not a sports vehicle although it looks a bit sporty. It has a regular 1.5cc engine with battery assist. Acceleration is quite decent in sports mode.
Mileage\Consumption- Not a true hybrid, but only IMA supported. I used to get anything between 12-16kmpl in city. (But once I went to f7 from dha-1 and it even gave me 21kmpl- Of-course the roads were empty) It depends entirely on how you plan to floor it.
Features, Safety & Breaking- It is well-equipped with airbags, traction control, key-less entry, three different modes, auto headlights, built-in hdd unit, navigation etc. . Braking wasn't very well, I was running mine of 18' low profile hard tires maybe that's the reason.
