The massive advertising budget for maruti suzuki, especially for newspaper advertising, is one of the reasons why Maruti suzuki is hiking car rates from january 2019. As mentioned earlier, it is advertising extensively in goan newspapers, with the same ad shown daily, in the paper.
It appears that the advertising agency as well as the marketing department is not monitoring the ROI on the newspaper advertising, so they are splurging money on advertising and then buyers have to shell out more.
The price hike is also advertised extensively,a showroom in panaji, goa had a big banner advertising the fact that the prices of the cars would be hiked from January 1, 2019 on 31, December 2018. They probably wanted customers to book their car before the price hike.
