The second-car market is a funny one. You've driven enough to try something bigger than a Corsa - now you're ready for a car that's more practical for long trips or carting stuff - only still cheap. Step forward the Astra - sheer numbers and reliability mean they can be found at bargain prices, while the handling, interior space and running costs are near class-leading. Best though is the engine - from the inside you won't even know it's diesel, yet it'll return 65mpg and torque to leave a grin.
