reviving car companies

In the recent years we have seen several notable car brands going into bankruptcy and then end up in the hands of Chinese or Indian companies. The prominent ones were Volvo, LandRover / Jaguar and MG. Volvo and MG were bought over by China companies while Jaguar/ LandRover were bought by Indian car company Tata.
All of these companies have now turned a new leaf in their business and are doing much better than when they were managed by their previous European owners. Why is that? Is it due to better management from the new owners or bigger injection of capital to boost R&D and product development?
From Volvo's perspective, having a Chinese owner helped boost their sales in China which is by far the most lucrative market in the world right now. The same goes for MG, being Chinese owned they were able to penetrate the China market enabling them to increase their vehicle sales many times over. Tata also did a fantastic job to turn around Jaguar / LandRover in the recent years. LandRover was stuck in a time warp with the previous generation models until Tata came along and took over the company. The new model line up was much more appealing to consumers and also created a new image for LandRover. The same thing happened with Jaguar, once deemed as an oldman's car is now much fresher and younger looking with several impressive new models that has given the motoring world some excitement.

Were the previous owners too stuck in their old ways or were they too cash strapped to make any progress? Getting into the two largest emerging countries in the world definitely helped and a positive change in management boosted the companies' ability to create fresh new products that people would want to buy.
