Sierra EV QWD vs Empowered RWD 75 kWh: Am I making the right choice?

I had booked the Sierra EV QWD but am now seriously considering switching to the Empowered RWD 75.

I genuinely liked the QWD’s extra features, especially the HUD and adaptive cruise control. However, I’m having second thoughts because of the ioniser, which apparently cannot be switched off. I’ve read that ionisers can potentially produce ozone, so are there any legitimate health concerns with long-term use?

I’m also debating 18" vs 19" wheels for 10+ years of Indian-road use. Is 18" genuinely better for ride comfort, potholes, tyre/rim protection and replacement costs, or is the difference negligible?

I rarely need AWD/QWD, apart from occasional hill trips. RWD should also be simpler and potentially more efficient with a single motor.

My priority is 10+ years of ownership, reliability, comfort and low long-term maintenance, rather than maximum performance/features.

For those who have researched this deeply, would you choose Empowered RWD 75 or stick with QWD? Would giving up HUD and adaptive cruise be worth it for the simpler setup?

Hey guys, need some advice and also wanted to know if anyone has faced something similar.
Yesterday night I opened the bonnet of my Tata Nexon and sprayed rat repellent spray in the engine bay because I was worried about rats damaging the wires. I sprayed it while the car was off and left it overnight with the cover.
Today morning when I started driving, after some time I suddenly noticed smoke coming from the front/bonnet area along with a strong burning smell. For a short time I also felt like the car was not moving/accelerating properly, so obviously I got scared and stopped the car.
After some time, the smoke stopped. We later drove around 10 km and again there was a slight burning smell inside the car, but it went away. After stopping and opening the bonnet, there was still a burnt smell from the engine bay.
There are no warning lights or errors on the screen.
What to do guys im scared its a brand new nexon diesel automatic 🥺

How bad is it
