Sir, congratulations in advance. Here are the answers to your question as per my recent experience:
1. What accessories, documents I should look forward to get.
A. Accessories: I got nothing from Honda Gateway. However, my friend got a complimentary key chain and carpet mats from Honda Point.
Documents:
a. Delivery letter by the showroom.
b. Warranty Book and Manual of car
c. Warranty Book and Manual of Sat Nav (if applicable)
d. The stub of your Pay Order will be stamped by the showroom as payment receipt.
2. Since buying it on OWN, is buy seller affidavit necessary or sale invoice/ sale certificate will be enough at the time of registration
A. There are two scenarios:
a. Open Invoice: You will receive the invoice in your own name from Honda.
b. Car booked in the name of an investor: I'm afraid I am not aware of the procedure in this case.3. What services I will get from showroom as its from them I am getting the car ( sort of)..... Initial running checkup? Etc etc
A. The showroom does a Pre-Delivery inspection. A guy will help you tally the engine and chassis number on the car with that on the Delivery Letter. The guy will also explain various functions, show you the tool kit and spare tyre, etc. ... and ask for a tip on your way out.
- What initial / immediate things to do when car is collected e.g oil change, tank full or not? Etc etc
A. You only need to get a tank full. Better to get the car filled with hi octane, so identify a petrol pump in advance, which sells hi octane. If not, identify a petrol pump near the showroom which keeps good quality petrol.
Good luck, share pictures of your car on this lovely website :).
