I want to buy a new car under 13000(euro),to last at least 10 years.What should i buy?

I was thinking at an ford fiesta. What do you think? Other suggestions?
I don't want to buy one that costs much to repair…

All cars you could buy new would be designed to last for 10 years
There's no way to know whether the one you choose, even if it is known as the cheapest to repair/service/run now will be that for you
You are asking for the immpossible - unless you have a crystal ball.

The Ford Fiesta would be a great choice! Parts are cheap and right now there aren't any reliability issues known. My neighbor has a 2011. She travels a lot so she bought one to help save gas. Right now it has well over 120 thousand miles and no major mechanical issues with it yet other than usual maintenance like tires and brakes.

I don't want diesel because i make around 10.000 km/year, and i want a new car, i won't buy second hand.

Well if you want any car to last 10 years you have to spend money for it through these years (service, breakdowns ect.)

Diesels will run more than petrol engines.

Ford fiesta is a good car, its also cheap to maintain, its pretty reliable. 1.6 TDCi is the best choice.
vw polo 1.6 tdi year 2010+ its very cheap to maintain and has good looks. And its spacy inside.
Vw golf 2.0 tdi year 2007+
