I've had a 1.8T SE for nearly 3 years now. It's a good enough car, not greatly inspiring but good looking and has proven reliable throughout ownership. It's ok on fuel, not really seen it as an issue. Built quality is alright. I find comments about the "hard plastics" you find in road tests on the MG6 a little odd as they have no more hard plastic than any other modern hatchback.
Ownership as been fine
Still have the 75 in the garage though!!
