Be careful when you deal with Varun Motors. They offer lot of stuff for "free" but you actually end up paying for it. Complaining to them is futile as they say their accounting practice is correct and Maruti Suzuki is aware of it. Their sales executives are aware but are forced to do it I guess. Get all rates/estimates/quotations printed on letter head. Get a copy of the invoice at time of delivery.They will retain original and will hand over after registration.
Check if the totals match.
