The O 403 is one of the most successful coach model designed and built by Mercedes Benz Türk AS.
This model was developed from the German designed O 303 coach. With modification and improvement by Turkish, it was given a name Tourismo to the market.
For Turkish domestic market, these buses were traded as O 403, while in other European countries, they were traded as O 350. Please see export Tourismos here.
In 2007, it underwent a facelift and the "New Tourismo" on this page is to distinguish from the original model. As in 2008, the Tourismo has taken a lion's share in the tourist coach market in Turkey and many European countries.
