4×4 diesel Ambience spec indian built Duster owner here. I have a 1st gen one affected by the rust issue. It has been repainted under warranty and after 3 months rust has yet to reappear. Still not happy with a new car rusting though so make sure dealer doesn’t try and fob you off with a touched up rusty one.
The 4×4 version has a stupidly low 1st gear which should only ever be needed off-road. I find it uncomfortable after a couple of hours on the motorway and I’ve never managed more than 45mpg. Tank is only 40 litres too so range is quite poor.
Boots nice and big but still needs front wheel off to fit an mtb in as back seat doesn’t fold flat. Road bike goes in complete no problem.
Interior quality is similar to a Renault traffic van, scratchy plastic but functional. Try and avoid having the central armrest as it gets in the way of the handbrake and seat recliner knobs.
