Hi Robert,

There was a wide range of engines and trim levels available in the 151 Leon, so it won't be easy to give you a good estimate based on the information provided. Nonetheless, 2015 Leons appear to be selling for around the €12,000 mark right now, so expect closer to €9,000 as a trade-in offer. That will vary massively from dealer to dealer of course so don't be afraid to shop around.
