My wife's E92 M3 with a manual has a remote start for over 10 years with zero issues.
OP, Fortin's remote starts work with manuals , i dont get it why some here are so scared, use common sense, not everything needs to ve idiot proof.
Longer doors also helps people get in the back seat, Jeep probably figured it's much cheaper to use the same doors from the 4dr
It makes it harder to get in the back...
