Hello, once again apologies for the lateish replies I'm not very active on the forums. Vezels are fantastic cars but as with any car you need to be sure it was maintained correctly and continues to be maintained correctly.
You can find me and a few other members on the Vezel forums talking about the DCT maintenance required to keep it running. On top of that you need to be sure your car has the recalls sorted out. I know of a place in Islamabad I-8 that does the software updates so that gives peace of mind to anyone in doubt if their car hasn't got it.
The car I believe is still worth it if you get it for the right price, so you'll be looking at 2016ish models. The facelifts imo are too expensive and the new one is out of the question. We used the car as our main car for about a year, but I do know the current owner quite closely, and I've been looking over its maintenance here and there. The car being a 2015 is still on its original battery, original gearbox and original engine. Last time I checked probably last year or end of last year it was at 240,000 and it's probably nearing 300,000 now. It had a clutch pack rebuild at about 220,000 or thereabouts. Clutches wear with time be it a DCT, Single clutch auto or a manual but for it to last as long as it did is still pretty good.
