I had an Octavia many years ago and went from a B6 Passat to the Leon.Did you swap to an Octavia after some time then?
Why do you say it was the wrong decision?
The Leon is a big step down quality wise IMO. I always thought of them as a Golf in a slightly less drab outfit for less cash but it generally feels a cheaper car. The rear leg room wasn't even a consideration two years ago as I stupidly thought that it made no difference with kids up to a certain age. I hadn't factored in just how big rear facing car seats are
The Passat, despite being a bit of a barge, was at least comfortable. The Leon really isn't that nice from a ride point of view. I could almost forgive it that if the trade off was that it was better to drive but before the Passat I had a Focus and that had the Leon beat on both handling and comfort.
As I say though, don't take my word for it as my one could well be a lemon and it also has the cheap torsion bar suspension setup at the rear.
