Scott...I only wish you knew the actual options on Regals. But it's cool...make it up as you go, none of these GP guys know any differently. Passenger could have a manual seat, chrome could be had on the bumpers of most of them and century's also had different bumper covers and side molding.
I'm consistent
See my siggy pic for proof. No doubt that the 92-99 Bonneville had the best seat of any car I've ever owned. The 00+ is good...but it's not 92-99 awesome.
let's add dual heated exterior mirrors
Autodimming exterior mirrors (optional)
Offset sunroof switch (I think that was so midget Grannies could reach it)
Fold down rear seat starting in 2000
Seat side airbag starting around 2000
and the most amazing cupholder ever (FWIW I never ever broke one, but fixed like 10 of them)
