Honda City ZX — price check / negotiation help

Hi, I am first time car buyer and looking for some help on what discounts can I ask for while negotiating:

Ex Showroom 16.18L
Logistic 5.3K
Tax collected at Source 16.1K
Road Tax 2.7L
Honda Assure Comp Insurance (3yr third party) 36.7K
Basic Accessory Kit 10K
[Optional] Extended Warranty (4th and 5th year) 12.3K
[Optional] RSA (4 years) 4.8K
HA Nil Dep Insu Policy Diff + Hydrostatic Lock CCover 13.6K

On road price: 19.96 L

Discounts offered:

  • From Honda side (I didn't fully understand this category): 25K
  • Ex-warranty: 13.5K

Final Rs. 19.5L

Location: Hyderabad

Question:

  • I am planning to visit a few more dealerships to get price, but also want to learn if I can get a better price, if yes what can I ask for?
  • The sales guy mentioned that he can get more discount after talking to manager but asked me what price I was looking for. I was a bit unsure at that point what price to quote.

Thanks in advance, strangers of the internet!
