So I was watching a movie, The Accidental Spy with Jackie Chan and this is the second time I see this, the first being in Endhiran (don't ask why). Anywho in both the movies, a sedan was converted to coupe and in both movies destroyed. In one a C class into a CLK (C209 gen) and the second movie an older E class into W208 CLK.
My question is, why is this done? Why not just get a normal CLK and destroy that

Unless the cars undergo more mods that cannot be performed on a cabrio.
Any ideas?
