Glickenhaus have already said they will miss the first WEC round at Sebring (if it happens anyway), I don't think they have built the first car yet, let alone a second one!
First car is being built now, testing scheduled for February/March after homologation.
Don't see Sebring happening to be honest.
There should be a "back-up" plan for the WEC test and first race in Europe around the same dates as Sebring, although in the current conditions with new lockdowns in the UK and an extended lockdown in Germany even that could well be in jeopardy.
