Errr... how about No. :no:
GM had a hand in the development of the S2 Elan... in the mid/late 80s...
Um, still not quite right.
There were S2's of the earlier Elans, and S2's of the M100 Elan. The S2 is not the designation for the M100 Type designed in the late '80's and sold in the early 90's, then later as a Kia.
'S' stands for Series, and series are generally variations within a Type. An S2 Elan can refer to either the original Type(s) and the Type M100.
There are also S1 and S2 Europas.
S1 and S2 Type 14 Elites.
GM assisted with the M100 and by default the S2 M100.
