yes thats a turbo, not much dearer but a lot more costly to run and insure, stick with the 1.8.
id personally never buy a vaux again, ive had a few and oddly the most reliable was a mk2 cavalier! but even that had its moments (ignition switch setting on fire and melting shround, and door lock fell into door)
i know people who drive nothing but vauxhalls, but then theyve never owned anything else to compare it to.
