Cost for CCA

Re: Employment expenses’ Motor vehicle CCA.

Client inherited vehicle (2011vehicle) in 2020. Had no employment expenses until start of 2022 where she became eligible for such claim.
Client used older vehicle to Oct 2022 and traded it for new one in Nov, 2022.
Auto-Trader presently list value of 2011 veh. at avg. $12,500
Client received $5000 for older vehicle as trade-in for newer one.

Do I really need value of older vehicle from 2020 or:
