Hi Diljit,
As the others have said, be happy you are here to tell the tale. It is a testament to modern car design and Euro NCAP pushing the manufacturers to improve passenger cell survivability that we have to thank for that, as well as the boys and girls back at the Skoda factory for putting the car together so well. I've dealt with some horrific RTCs in my time, seen wreckage that you couldn't believe anyone could possibly survive from, and yet they've often walked away with barely a scratch! I once had the embarrasing situation of attending an RTC on a dual carriageway, a car versus a lorry, and called it in as a "Smart Car", then my buddy walked over and said "Er, it was actually a Peugeot 406 big man!". So yes, be very thankful that you and your passengers were protected by your baby. I used to find at RTCs that people got so irate about their car being smashed, of course it was partly the shock of the incident, but the easiest way to put things in perspective was to say to them "Yes, but the car did the job it was designed to do: protect you and your passengers. And bear in mind, it can be replaced, you and your passengers cannot be replaced". That usually gave them food for thought.
As far as replacing it, well, I'm biased, I've been a Skoda owner since 2001, so only 21 years, and they are beginning to grow on me! 😆
Try and get a vRS if you can, the 2013-on model is definitely the pinnacle, especially if you can find one with a host of extras!
Good luck with whatever you go for, professional curiousity makes me want to ask how the incident happened, but it's probably better for you just to let it lie. The one thing I would say is get behind the wheel as quick as you can, a prang like that can sometimes dent your confidence.
Take care, stay safe.
