Advice needed for Changan Alsvin

Hey guys, I have a budget of around 3.5M-3.7M and after alot of searching finally decided to go for Alsvin 1.5 DCT Lumiere. Just some queries from owners:

1. what is the maintenance costs as compared to other cars in this price range?
2. after market services including repairs and availability of parts?
3. any known issues or general feedback would be highly appreciated.
