Unique Buying Situation

Hello!

Currently in a unique situation where a relative is offering to buy a car outright but i'll be moving in a year and will need to sell the car after a year. Unfortunately the conditions are strictly that I buy a car or I get nothing. The car also has to be new or newish and I can't spend less on the car than i'm receiving. I'm not allowed to lease/rent/etc. If the offer for the car is in the $30-40k range, what is the best way for me to navigate this so that I can recoup as much of the cost as possible when I sell it in a year?

Weird situation but I was wondering if anyone had any ideas on how to best approach this? The best I have come up with is to buy something with the best resale value ex. toyota and just drive it for a year and then sell.
