The Citroen C5 Aircross is available in a single variant and its on road price in Champawat is ₹46.34 lakh (including all taxes, RTO fees, and insurance).
Your shortlisted cars vary widely in price and category, ranging from Rs 15 lakh to Rs 75 lakh, including ICE as well as electric cars, so it's hard to pinpoint exactly what you are shopping for. If you plan to do long trips, avoid an EV, as it is just not worth the hassle, given the current state of charging infrastructure.
The Citroen C5 Aircross has astonishing ride quality, since that is your primary requirement, but bear in mind that dealerships are few and far between, and the model itself is now dated and due for a replacement.
If you move to the upper end of your budget, consider the Audi Q5, which, though also a bit long in the tooth, has excellent ride quality and is an excellent value for money.
Similarly, the Jeep Grand Cherokee is a full-size SUV with excellent ride quality, with prices from a segment below, and is also definitely worth check out.
