"It's very difficult to explain what attracts me to these cars. Apart from being my hobby, the happy memories attached to owning them in that day and age keeps my passion alive," Mohan told the Times of India on the sidelines of the vintage car rally.

After organizing '21 Gun Salute Vintage Rally' which presented automobiles of the bygone era from different parts of the country, including Delhi, Gurgaon, Mumbai, Kanpur, Jaipur and Chandigarh on Sunday, Mr Mohan said that the rally was a result of the positive response of the previous rallies.

"The mission is to extend the experience of the old bygone era with a contemporary touch to re-live the royal and aristocratic history of our country," Mohan said, adding, "Not only these cars represent India's heritage but also showcase the evolution of the automobile industry in the world in last century."

Collecting such a huge number of cars and bringing them at one place, Mohan believes is a much difficult task and needs a lot of hard work. "It's a dream of every car enthusiast to find a long-lost car. But, this doesn't happen very often. You need a lot of legwork and need to meet a lot of people to find one such car," Mohan said.

He also believes that without passion this task is impossible and he is able to achieve so much only because he has grown up with such a passion inside him and around. "Car collection and restoration is something which is not possible without passion. Now, when I showcase the cars and youngsters appreciate it and click photographs, the feeling is amazing," he added.

Collection of such cars, according to Mr Mohan is just a beginning of the hard work as maintaining them is also a huge task as it is difficult to find spare parts. "Maintaining vintage cars is not an easy task. They need a lot of care; even when they are not participating in rallies. They have to be checked every week for any discrepancy in the machinery and the outer body," he said.
