BB00332 (and other individual car loans)

Just reviewing my loans coming to an end shortly to decide if I wish to renew or not. In particular BB00332 (2016 Mercedes), presumably the value will have depreciated in the six months since inception, so how will the renewal work (if there is one)? Will the LTV increase above 70%? Or will the borrower have to pay a fraction of the loan off to compensate for the reduced security value?

And further, this is a loan where it is said your "motor trade partner who in the event of default by the borrower will purchase the vehicle at the loan amount". Does this 'agreement' get renewed at loan renewal, as presumably the deal is worse for them if the car has depreciated?

Thanks.
