Is a second hand swift a reliable option ?

I am looking to buy a cheap second hand car (3k top end of my budget) that is reliable and cheap to run. The car will be used as a second car mainly used for short journeys to train station and back with occasional motorway usage, I have been having a look and there seems to be a good range of second hand swifts in my price range. Is there any pitfalls to look out for or years/models you would recommend, or other options that you think fit my requirements ?
