Investigators with the fire brigade stated that they believe the fire began with an accidental engine fire in the Range Rover at about 4.30 pm.
Mayor Anderson told Heart an under-resourced fire service was a bigger issue, he said: "We only had two appliances that turned up initially. and two years ago there would have been eight".
The Association of British Insurers (ABI) estimated the claims figure following the 1,000-degree Centigrade blaze that took hold of the Liverpool Echo Arena's vehicle park during the final event of the four-day Liverpool International Horse Show.
The evening performance of the Liverpool International Horse Show that was scheduled to take place at the Echo Arena was cancelled as a result of the fire.
Nobody got injured, be it humans or horses.
The multi-storey auto park at the Arena and Conventions Centre (ACC) was full of 1300 cars, all of which were totally destroyed in the blaze.
The Mayor of Liverpool, Joe Anderson, tweeted that not enough fire engines responded to the incident because of cutbacks. The popular horse show was cancelled because of the fire, which was brought under control early Monday morning. "We would also like to thank the people who kindly provided transport for customers to enable them to travel home, as well as Liverpool City Council for establishing a relief centre for those needing shelter".
"The announcer then advised us all to go and get a coffee or do some shopping while emergency services put out the fire. Very proud of all the staff who work there", he tweeted.
The horses were moved to safety inside the arena.
Hoardings are set to go around the building from this weekend, following the devastating blaze on New Year's Eve.
ACC Liverpool told Pollstar in a statement that its events program will proceed as planned at Echo Arena.
It said it was looking at alternative parking for its forthcoming events.
Next up on the arena's schedule is "Fast and Furious Live", Jan. 11-12, followed by "Celebrating Sgt Pepper: Live on Jan. 13". We ask for everyone's patience and understanding while investigations continue.
