Looking again at the data presented. Missing are armoured cars / wheeled recon vehicles, but APCs are included, so the emphasis is on actual fighting vehicles and APCs.
Totaling the number of APCs that are repairable comes to around 500. The Soviet Union did not produce APCs during the war, and when it could get them it used US half tracks and a smattering of Universal carriers. 500 APCs would be a useful asset if able to be put in service and used in one unit, or split between two units.
That would give, in general terms, two armoured mechanised Motor Rifle Brigades of infantry that could be attached to Tank Corps, a useful addition if things went hot between the Western allies and the Soviet Army in 1945 and with mobile warfare taking place.
The Soviets were not exactly in the forefront of APC development: Post war the initial APC was the BTR-40. that could be considered as the equivalent of a long White Scout Car.
(wiki, yes I know: notes about the White: that the Soviet Army received 3,034; these vehicles remained in service until at least 1947)
The next Soviet APC, the BTR-152 was virtually a wheeled M3 Half track. Then again, form follows function. But the BTR-152 was concurrent with the US M59 APC, which shows quite a difference in doctrine and design. The Soviet Union received around 950 M5 half tracks both during and after the war.
So having around 500 extra armoured personnel carriers available to the Soviet Union in 1945 should not be discounted.
It should also be remembered that Czechoslovakia (as it was, and a member of the Warsaw Pac) produced a copy of the Sd.Kfz 251 as the Tatra OT-810, which if anything shows that what resembled a German APC was still possibly useful in the 1950s.
