Which used MG ZT saloon should I buy?
Your best bet by far is the turbocharged 1.8-litre petrol engine. Its 0-60mph time of 8.5 seconds isn't too far behind the bigger 2.5-litre V6 engine, but you'll travel an extra nine miles on every gallon of petrol.
The entry-level 1.8 is even more frugal, but it isn't really fast enough to live up to the ZT's sports saloon billing. The same goes for both the 2.0-litre diesel engines.
