Hi Tmm, The reason I say that is because the spec for the Glam and Slam isn't much differentso that's why I wonder why they class the Slam top of the range over the Glam, when I originally ordered my car way back in March the Glam didn't come with a panoramic roof for example and I opted for one and 17inches wheels which gives you the sports suspension, I also went with mud flaps, sports pedals, the intelilink stereo, full leather seats and the winter pack which gives you the heated seats and heated steering wheel, when you look at the spec on the Vauxhall website now it suggests that the Glam and Slam are both the top of the range over the Jam and differences being one has the 17 inches wheels and sports suspension and the other the glass roof, it does say that the Slam has map pockets in the back of the seats and tinted windows but mine has both of them as well.This is taken from the Vauxhall WebsiteGlam additional Features over the Jam[*]Electronic climate control (ECC)
[*]Fixed glass roof panel with sliding blind
[*]Drinks holder in front centre console with adjustable restraining strap
[*]LED daytime running lights
[*]LED rear lights
[*]Chrome-effect upper side window mouldings
[*]Chrome-effect door sill covers
[*]Body-colour door handles with chrome-effect insert
[*]16-inch ‘Vintage' alloy wheels.[*]Sports suspension

When all issaid and done you can take any of them and make them better than each other so why just not have one model and spec it the way you want.
