Sorry for what seems like "whipping a dead horse". But there's one more reason it's sad to see the new Challenger is actually going to be a "post sedan" car. When ever the engineers depend alot upon using the "B" pillar for their structural integrity, it just makes it that much more costly to transform that same design into a convertible.
If they had built it as a true "hardtop" from the get go, it would be far more likely that we might see a topless Challenger. After all, they'd be half way there. Just my $.02
