Which used Rover 25 hatchback should I buy?
Not the turbodiesel. It's like diesels used to be before they got smooth, strong and refined. Worst of all, you'll probably pay extra for the privilege of being saddled with the worst engine.
All of the petrols (1.1, 1.4, 1.6 and 1.8) are eager, while the 148bhp 1.8 VVC turns the 25 into a respectable hot hatch. They're also economical, but our money would go on the 1.4.
