Hello chaps,
I'm getting a mobile service on the go for the latest secure processors etc and I'd like your input on the design for the van - it's booked in to be done next week.

Looks good but my comments would be:
1. Watch the typo on 'guarantee' over the left indicator and on the back doors. Currently reads '100% satisfaction gurantee'.
2. I'd take 'Carbon' off the GTD plate. There is a lot of visual clutter on the van already and it's a bit like a billboard, people are going to get a fleeting glance so you need to make sure that what they read counts.
3. Typesetting is slightly whimsical - emboldening words for emphasis is fine but why bold 'rolling' and not road. No problem where you have 'more power, more torque' because the emphasis is right.
4. Why not change the livery of the van and brand the vehicle as 'Mobile Service Van' or something instead of stating 'Mobile Service' as a benefit.
5. Why have the address on the van? If people want to find you, they can go to the website or pick up the phone. Nobody is ever going to write down an address off a van but they might take a phone number or url.
6. Possibly put the marques you deal with or specialise in on the vehicle - just logos somewhere, people will join the dots. Otherwise they may not think it's relevant to them or assume that you just do diesel Golfs.
