Do you live in Italy, Kelly?
I currently have a 1.8, but have driven a 2.0 before. You can definitely tell a difference, the 1.8 is more peppy and has a great pick up. But since it has the turbo, that means more parts could potentially break down the road. But really, it's more fun so who cares
As far as leather vs. cloth, it's really a personal preference. If both cars are in the exact same shape cosmetically and have low mileage, I see no reason why you wouldn't want to go with the 1.8.
