Hi, stuck on two, both cryptic: 20 across, prize outsize vehicle (5), I have ?s?a?

Also, 19 down: pleasant sort of soft drink (7)' , I have ?o?d?a?

Could someone also please confirm whether a Christmas cracker proverb is called a motto. Have never heard it called that before but it fits !
Five letters m?t?o.

Many thanks, hope you're all enjoying the snow!
