I'm in agreement with the others in this thread that the brochure in question was a bit dense on the load times. The idea is nice, and it would be something I wouldn't mind being able to toss to my customers, but as it sits it's a little heavy on the loading and reading, and a little light on pulling people back to my inventory.
I like this layout quite a bit more; more compact, tighter and much nicer overall. Although, in both cases a lot of the links back look and feel just slapped on and very repetitive and heavy handed; maybe it's me viewing it at 1600x900 and 1920x1080, but the resolution difference between the actual brochure and the added graphics is pretty abrupt, unclean cut lines (grey shows at button edges on "View All Inventory") and a lot of the graphics look like they had a little too much compression and smoothing done to get them to size. It makes me feel like I need glasses until I look at the text and everything's kosher again.
If I were shopping for a product like this, I'd prefer a richer color palette (manufacturer brochures can be an ocean of grey) and maybe to double up the first page to be two pages side by side, and the second page to dive into trim levels and specs. I get that you're a little limited based on the source material, but this is me speaking from an ideal standpoint for what I would want.
Right now we use VIN Brochures for used cars with the Motosnap/VIN Solutions CRM, and occasionally for new as well. Our customers seem to like it well enough, but our used cars also have 40+ pictures crammed into that email as well, and we've got 12-18 of all our new as well to get added in. It gets a little heavy at times, so something that was maybe a little more concise or size-controlled like this would be a nice thing to see.
