Mercedes-Benz sprinter van roof height

[Ironside]

I have got an order a standard roof sprinter van. Something has got me a little worried. I've got the catalogue here and it gives you all the dimensions of the vans. The van itself is 2435 mm high. From the floor to the top of the door at the back it is 1650 mm high. In the middle of the van from floor to roof it is 1520 mm high. What I am worried about is if it's going to be a lot lower in the driver's position. I will be driving the vehicle from a wheelchair and I'm quite tall. I can get into the van okay but I'm just worried that my head is going to touch the ceiling in the driver's position. I need at least 4 foot nine. Anybody have any ideas?

I'll slide your query over to the Sprinter section for you, where you're more likely to garner a helpful response.

I didn't know there was a sprinter section, where is that?
