The Deere dealer would have done a better job if they quoted you a price on the 5045E which is a little larger than the Mahindra, rather than the 4052M which is a little smaller. The 5045E is a noticeably simpler and less expensive tractor than the 4052M and matches up to the Mahindra in price and features much better than the 4052M does. Generally the dealer pays somewhere between 70-80% of the MSRP for the tractor. They should have given you a quote that was less than MSRP. 30% less than their quote would be quite a bit less than what they paid, they would be selling at a decent loss. Your number was so low that they probably didn't say much because they were so far apart on numbers with you.
There is always room for competition but it looks like there isn't nearly as much room for (another) foreign tractor maker to come in and clean up like there was in the domestic auto industry in the 1970s. The foreign automakers in the 1970s didn't just sell cheaper versions of the current American large sedans, they sold something that was primarily completely different and more applicable to the current situation and was also cheaper. The smaller tractor manufacturers sell either noticeably simpler machines for noticeably less, or sell a comparable machine for a little bit less. Making simpler machines won't make a big splash in the market as unfortunately the buyers generally keep wanting fancier machines (just look at what is posted here, there are people who won't mow their yard unless they are in a cabbed machine) and there are generally enough simpler tractors already out there to take care of much of that market. It would take something the big players aren't making to really break into the market. For example, if a foreign tractor maker figured out how to meet Tier 4 emissions with a regular ol' Stanadyne injection pump and nothing between the exhaust manifold and the end of the exhaust stack except a muffler, and made the same power and got the same efficiency as everybody else, they would clean up.
The foreign auto makers did have to deal with emissions like the domestic auto makers, but it was easier to push a little tiny, light crackerbox of a car with an emissions-strangled engine than a big, heavy full-sized car. There was also the expectation of poor performance right out of the box. You expected poor performance out of a cheap little crackerbox, so when you got it, you weren't disappointed. You were disappointed when the 1975 version of the same model you got in 1970 was a dog in comparison.
