No cars in the box - it's the garage structure only. That said, it works with most standard small toy cars, so whatever's already sitting in your child's toy basket will likely slot right in. Hot Wheels and similar sized cars are a good match.

18 months and above. The ramps and parking bays are straightforward enough for toddlers that age, though a lot depends on the child. Some 18-month-olds will get it immediately; others need a few months before they're really playing with purpose.

Both, according to the listing. The plastic is durable enough for outdoor sessions - a shaded verandah or garden works well. Just don't leave it in direct sun for extended periods, the colours can fade over time with any plastic toy.

Bit of both, really. Parking cars in specific bays, moving them between levels using the ramps, and organising the "service zone" builds hand-eye coordination and basic spatial thinking. Kids also tend to make up their own stories around it, which is good for language development. But mostly they just like the ramps.

Easy to assemble. No tools are specifically mentioned, though it's worth checking when it arrives - some playsets this size need a screwdriver for one or two joints even when the box says otherwise. Shouldn't take more than 15 to 20 minutes either way.
