6k miles in my 1l Karoq SE Tech since March, including a couple of long trips.
I'd agree about the wipers, I can't understand why my previous two Mk3 Leons, and this Karoq all have noisy wipers when the wipers on my partner's Golfs (Mk7 and Mk7.5) have been completely silent.
Seats I find pretty comfy, longest journey in one hit was 200 miles and I felt fine after it.
No mystery noises, overall very quiet apart from a bit of booming if you travel without the parcel shelf in place.
The engine is an odd one. My worry before I got the car was that it would be out of its depth - it absolutely isn't, and will happily sit in the outside lane at 85 - 90mph (where legal ) all day long, and for my day to day use + commute it's fine. A trip to the Yorkshire Dales showed its shortcomings though - short straights, lots of bends, climbs etc had me constantly changing gear, or being caught in the wrong gear.
Long term consumption is an indicated 45mpg. The engine just seems a bit pointless in this application really - it's not the economical option (I'm convinced I'd get better mpg with the 1.5l engine), so the only benefit is cheaper purchase price + insurance costs.
The only toys I really miss on this spec are the auto near side mirror for reversing, and LED headlights, it's got everything else I need.
