Just traded my 1.4 TSI Octavia III for a 1.4 TSI Seat Ateca. First impression - the Seat rides the bumps better and there is no sign of the low frequency boom that plagued so many Octavia owners. Mine didn't really suffer the boom (which I witnessed in other people's) but it did have a slight cabin vibration when driving over minor ripples on uneven roads. This is not present in the Seat, which makes for a better driving experience. The Seat seems a little sluggish when trying to accelerate from low revs compared to the Octavia. I never disliked the Octavia, but I think the Seat might have the edge.

 

I'll probably still sneek a look on this forum in the future, being as it's virtually the same car. 

Enjoy! I quite like the look of the Ateca. It's also built by Skoda so you still technically have one
