Should I buy a used XUV700?

Hi everyone, I was recently browsing through the available used cars on olx and found 2 dealers that have 2 "decent" XUV700's for sale. Kind of confused whether it is a good idea to consider them and would like to know your thoughts on this.

Some context, I was looking to buy a brand new XUV700 (AWD AX7L AT) but decided to check the used car market and saw 2 good ones (~50% savings) so considering to check them out.

  1. 2022 AWD AX7L Diesel AT

This has run ~40k kms and looks to be in good condition. Funny enough, this is the exact spec that I was thinking of buying the new one (silver AWD AX7L AT) and I am really tempted to check it out. The asking price is 17.5lakhs though it's negotiable.

  1. 2022 AX7L Petrol AT

This has run 22k kms and looks to be in even better condition than the above one. I am okay it being a petrol. The only reason I was going to go with the Diesel (if I buy a new one) was AWD. I am actually more inclined towards the petrol. Asking price is 16.5lakhs and it's also negotiable. Given that the price is quite good, I am willing to overlook the fact that this would be a FWD.

I am planning to check these 2 out tomorrow and if things go well will probably also get it checked by a mechanic (open to suggestions, I am in Guwahati).

Let me know what you guys think and any potential things that I should be in the lookout for. I have already spent some time to go through the team bhp guide on checking an used car and I feel like I am fairly confident on checking them out.

Also, for both the cars, I asked what is the reason for selling. The 1st one said they don't know (they are a dealer) and the second one said that the owner bought a 4x4 scorpio n (which sounds very reasonable).
