I own an MG HS, it's 2021 model, switched from Civic, i also own Sportage, Prius and a small car,
Comparison :
In term of features, comfort and mileage, i prefer MG over sportage and tuscan (these are C/SUVs) you can't compare it with a sedan. I am getting 10 - 11 km/l in city and 13-14 on long from my MG, whereas, 9-10 km/l in city and 11-12 km/l on long from Sportage FWD 2021 model
After sales :
Now parts are readily available, obviously bit expensive (for all the C/SUVs same situation)
Resale :
Resale nowadays is pretty slow for all the vehicles above 5m+
Conclusion :
If you want features and convenience, go for MG, if you are conscious and of typical mind set go for Sportage.
