Hi Tonmoy,

It's very difficult to predict how much you'll be offered for your Corolla as a trade-in, regardless of how detailed you are with the car. The truth is, with older cars such as that, dealers are not likely to offer a huge amount, and that amount will vary depending on how badly they want to make the deal. 

To sell it yourself, you'd possibly get €3,000-€4,000 if you're patient, but expect half that from a dealer as a trade-in. The 2013 Auris Hybrid isn't very common and is likely to be priced in and around €9,000-€10,000, so your cost to change will be €5,000-€7,000 depending on all those factors.
