No.
Traditionally bank loan is 90% of car price.

But full loan these days are done via markup on their invoice. With the implementation of e-invoicing, this cannot be done anymore. Hence full loan will not be possible for new cars.
Used cars and recon still possible.

Yup.
Previously the invoice they issue is mark-up from "accessories".
Now cannot be done, unless they want to pay tax for these "mark-ups"

Possible, is up for discussion as there is no fixed price for recon & used cars, unlike new cars.

Most didn't know that car tax is actually the country's golden goose.

Of course.
Just higher car price, but full loan.
People will still buy.

The problem is the introduction of HVGT, which will put a 5-10% increase.
