How much do you earn per sold car relative to its purchase cost?

[Nico 33]

I only have one R5 already in use, but I want to take part in all daily events and one requires a R5. Can I buy one, use it and sell it without losing too much CR?

If I remember correctly, it is somewhere around 75% of the purchase price. No idea if damages impact the final sale price.

The "buy for full, resell for 75%" was a common tactic when trying to burn the extra 2 million credits you get when you bought GOTY edition.
