Try to look for it by Fiat motor repeats the engines a lot, example of this is the brave, which is equal to the brave, Palio Palio Weekent and thus, they bring a description plate that will tell you if it is an A4000 or something.
Look: I don't know what country you are.- I am from Argentina and here is a rather common car. The Adventure version is the largest version of Rural Pallium or Break (the country depends) 5 doors in the version you name has larger tires as for off -road use and a major clearance of the soil is to say is a little higher than the rest of the versions. Then in regards to the rest of the mechanics it is the same as that of normal palates both 3 and 5 door or the version with Baul here called Siena. You do not measure where you are and do not mention that Version of Adventure and Year you want to buy. The motorization was varying depending on the year. You can get it with 1.4 8 valves, 1.4 16 valves, 1.8 16valvulas and 1.7 Turbo Diesel. In all cases the mechanics is normal and simple to any low -end car or at most. He has no big problems. You say if it is easy to repair but in mechanics most of the engines have great similarity except for external accessories. In this case, the greatest difference can be in the suspension part that uses shock absorbers and springs other than the rest in addition to some small reinforcements (not mugo) except for it the rest is common. Greetings and luck
