New Grand Scénic Exception with Executive 1.5dCi – Questions about equipment.

Hello, after 8 months without Grand Scénic I might want to order one again. Since I am very satisfied with my 1.5dCi in the Mégane so far (motorwise), I will order a 1.5dCi in the Grand Scénic if it really comes to that. I don’t need more for the 90% country roads … My dealer managed to make me an offer again, with which I can almost not say no.. But now to my questions, which I can’t get answered in the configurator. : – Are there actually partial leather in the executive? – can you order heavily tinted discs (pages/backs)? They are not in the configurator… do you know what this option costs? – which 16″ rims are in the Exc.Exe 1.5dCi? – can you retrofit the roof gallery later? So, that’s it first… Thank you!
