BUENOS AIRES, March 15 (Reuters) - Argentina's economy may be stagnant but the capital city Buenos Aires is looking better than it has in years, boosting the popularity of its mayor as he prepares to run for president in October.

Mauricio Macri, a conservative businessman, has built a strong power base in Buenos Aires and is one of three leading candidates in the race. Some polls show him in first place.

Opponents say he would neglect the poor and side with big business and foreign bondholders, vilified by the government as "vultures", who are suing Argentina over defaulted debt.

But polls show Macri is the candidate most identified with change in a country where more and more voters want just that.

The 56-year-old former president of the Boca Juniors soccer club has been Buenos Aires' mayor since 2007 and has a reputation for getting things done.

Hundreds of thousands of commuters have been helped by a "Metrobus" his administration introduced on the capital's main avenue, separating bus from car lanes and unclogging both.

School nutrition programs, bicycle lanes, pedestrian malls and parks with health stations where people can check their blood pressure have flourished.

Investors lapped up a $500 million municipal bond sale this year even though Argentina has been shunned by global capital markets.

"Generally, we don't trust politicians. They offer you 10 pesos so they can steal back five. But Macri has invested in a way that has improved the city," said Maximiliano De La Torre, a hair stylist who lives in the middle class neighborhood of Villa Crespo and works at a salon in ritzy Recoleta a few miles away.

Macri says he would open Argentina to foreign investment by easing strict trade and currency controls that have hobbled the economy. Still, after eight years of heavy spending by President Cristina Fernandez on popular subsidies, he may struggle to overcome fears he would impose painful austerity measures.

Fernandez is barred from running for a third consecutive term. Polls show two thirds of voters want a break from her interventionist policies, including controls that restrict access to U.S. dollars, but they do not want to scrap the social safety net that she helped strengthen.

Macri has not said how he would reduce state spending without hurting the economy. He instead promises to cut the need for welfare by attracting the investment needed to bolster industry and create jobs.

He also pledges to respect the central bank's independence and its role in controlling inflation.
