<font size="2" face="Tahoma">Bueno was very talented and became one of the top drivers in domestic racing in his native Brazil.
He twice won the Brazilian touring car championship and, in 1969, he travelled to Britain to race in Formula Ford, courtesy of a Brazilian government scheme. He won five races and was well placed elsewhere with a Merlyn, but opted to return to Brazil and continue in domestic racing in 1970.
Regarded as highly as Emerson Fittipaldi, Bueno was keen to take up an offer of a full-time return to Europe in 1971, but could not come up with the budget. He thus ended up driving a works March in Brazilian Temporada series with some success.
He did compete in the inaugural non-championship Brazilian GP in a private March 711 in 1972. He qualified 10th and finishing sixth, though only six car were classified.
His only Formula 1 World Championship Grand Prix took place the following year at the 1973 Brazilian GP where he qualified an aging rented Surtees TS9B-Ford at the back of the grid. He finished the race four laps down in 12 and last place.
