Trade buyers will be allowed back on site at Manheim Auction Services' sites in Bristol, Manchester and Washington to help dealers source stock for their used car forecourts.
It follows the earlier reopening of Manheim's Colchester, Birmingham and Leeds motor auctions.
Since the coronavirus pandemic hit the UK, much of the used vehicle remarketing has remained exclusively online or vehicle viewings have been by appointment only.
Liam Quegan, managing director at Manheim, said: “With used car demand at record highs, it is more important than ever that we help connect dealers with the right stock across a choice of channels.
“With more physical auction centres now open, more than 50 sales each week and further investment in our existing digital platforms - including Simulcast – too, Manheim is providing a flexible sales programme that reflects the needs of sellers and buyers.”
No pre-registration is required to attend physical auctions, but buyers are asked to respect Covid-secure measures for the protection of everyone involved - more information is at Manheim's coronavirus hub.
