I don’t see a post on Maruti under investments. However I think this is a great company to explore. The NPM surge has been significant in the last few years. The capacity is still lagging demand and true potential of MSIL can be seen only when they are free to sell all variants with differential margins. For example, they stopped selling hatch back diesel (Ritz) to cabbies due to production constraints. They have to focus on higher margins and ignore selling lower margin cars.
A close look at their market share growth and sustinance would be very helpful. What is more interesting is the pipeline of competition. Barring a few models from Hyundai and Tata, Maruti continues to have a free hand. At current valuation, one can look at estimating EPS when capacity > demand.
