The trailer was taken from M1 Taxis' site on Liberty Way on Friday 23rd April just before half 7pm.
The trailer is described as a 'Brian James Racing Trailer' which M1 said is worth in excess of £6,500.
The firm is offering a £5,000 reward for information which leads to a conviction of whomever stole their trailer.
John Igoe, owner of MI Taxis, said the thieves waited outside the compound for nearly 45 minutes before racing in to take the trailer.
"They were in and out in 27 seven seconds", he said.
"The footage shows the car drive in and then leave quickly at quarter to 6, as if they'd made a wrong turn.

"But they parked up across the road...the site was busy at that time with cars coming and going, so they could have been waiting for the best moment.
The thieves were in such a rush that they left without raising the jockey wheel, which is used when moving the trailer to and from the vehicle.
Someone from the firm chased after the car, but lost track of them. The car was reportedly seen in Coventry 20 mins later.
John said the reward is not necessarily about getting the trailer back, but rather seeing that justice is done to whomever took it.
"If they've taken it and cut it up for scrap so be it, but I want to get them into court and have them named and shamed."
A Warwickshire Police spokesperson told Fosse107,
"We were called at 8.17pm on 23 April to a report of a theft on Liberty Way, Attleborough Fields Industrial Estate, Nuneaton.
"It’s reported a trailer was stolen from a premises.
"Enquiries are ongoing to locate the trailer and identify those responsible.
"If anyone witnessed the offence please call Warwickshire Police on 101 quoting incident number 431 of 23 April 2021."
