Likewise from me, Guy.Hopefully you will still get over and if so the car place I was trying to think of is Easycarental they have a web site at www.easycarental.com (note ony one 'r'). The offer is a Merc. A class for 7 UKP per day between October and December. Dunno what the catch is.
Good luck, hoping you are not badly affected and thinking of all my American friends in their time of crisis.
