Major Mercedes-Benz dealer Han Sung Motor carried out a second city project on Thursday night, helping to refurbish Guro Station.
students joined local artists and citizens to turn the old subway exit into a place of art.
The old walls now feature colorful pictures reflecting the community, which has developed from old fabric factories into a digital cluster. The street has also been refurbished.
Local artists also paired with former fabric factory workers to display their works. "Following last year, when we worked on Seoul Jungang Market, we hope this year's event will bring positive changes in the local community," said Han Sung Motor chief executive Ulf Ausprung, who attended the festival-like event on Thursday.
Han Sung Motor has been running the Dream Gream program since 2012. Young people from underprivileged families develop their artistic talents, with employees mentoring the youngsters. The program, which started with 20 students, expanded to 40 this year.
The German CEO said, "This has nothing to do with our business. Han Sung Motor has been 30 years in the community, so we wanted to do something for the community and it should be something long lasting.
"We have supported these students from elementary school until they graduate from high school. When they stand on stage on graduation day, tears in their eyes, saying Dream Gream changed their attitude and the way they look at the world, you are standing there and saying, yes, you are doing the right thing."
Last year, the Seoul Foundation for Arts and Culture also began art projects to improve the city's landscape.
"We started with the small project last year at Seoul Jungang market," Ausprung said. "Market people came to me, to touch me and thank me. It was a small contribution.
"This inspired us to do something bigger this year. We are not looking at a side benefit of selling our cars. This is something straight from the heart.
"We will spare no effort in helping our Dream Gream students share their talents with the local community and spread the values of art in everyday life."
