What country are we talking about? In north america, all trim models except the LS are 1.4 turbo. If you've got the VIN, you can probably plug it into a decoder and see what the VIN says.

The main thing I'd look for is regular oil changes. I wouldn't call them fragile, but i don't think the turbo is terribly forgiving of oil abuse.

It says "LS" not "ECO". LS is the bottom level trim model. It may not have cruse control.

Do take it and others like it for a test drive. The 1.8 and 1.4T has the same horsepower, but the 1.4T has more torque at the lower RPM making it a nicer engine.
