If you want to be truly stylish when carrying all the various fluids, tools,
towels, etc, find a suitcase of a vintage appropriate for your car. The makeup
cases are great for the bottles of oil, ATF or washes and waxes. It looks much
better than an old cardboard box or milk crate when you have the luggage
compartment open unloading at the elegant hotel where you're staying.
Cheers,
