Should you buy a vauxhall Astra or a corsa I have about 4000 tp 4700 to spend and do a lot of motorway driving?

The Astra will be much better as you will mostly drive on the motorway however it will cost more as the lowest amount of litre for a Astra is 1.4 and a corsa is 1.0 but a Astra will have more expensive insurance and road tax and petrol however the Astra is a very reliable and strong built car but I will advise you to buy a Audi a3 or either a VW Golf new model.
