whats the difference between a celica supra and a supra?

[tone loc]

Im not sure if your asking but the diffrence between the the celica supra and the supra is this.

The diffrence is markI and MarkII are celica supras
markIII and markIV are regular supras

MarkI is from years 1979-1981
MarkII is from years 1982-1986.5
MarkIII is from years 1986.5-1992
MarkIV is from years 1993-1998 (Japan went up to 2002)

so from 1979-1986.5 are toyota celica supra
and then supra branched away from celica in 1986.5 and became just supra
