why not give the 222 the protoss regenerating shield ?
222 could be easily balanced against that by giving it wraithbone or living metal chasis, which would self regenerate all the time.
I'd replace turret weapons so instead of mg34 and 20mm autocannon it can have scatter laser and pulse cannon, this would bring its AI and AT performance on a sifficient level with other scout cars.
Low mobility and cover collisions could be addressed by slightly reworking suspension into a skimmer.
It could look something like this with these slight modifications and finally it would be worth all of that sweet 30 fuel for all the anti air, anti infantry and anti tank capabilities it got:
