Good day muxers (Sorry for the terrible term

)
After going over this thread, I have decided to choose isuzu mux LS-A M/T obsidian grey as my 1st ever brand new auto. Hopefully, I could get the unit this weekend.
PSBank - 21,582 for 5 yrs, free chattel, free insurance 1st yr
Isuzu Quezon Ave. - 255,600 as 20% dp with free 3 yrs lto reg, 20k discount, tint, mats, seat cover
I have to admit that I am not a guru when it comes to cars so can you please give me some insight as to what must be inspected upon receiving the unit from the dealer. Please bear with me.
Has anyone here bought from isuzu q. ave? What can you say about their after sales service?
Thank you everyone!
