My last two convert rentals had minimum trunk(dodge thing and ford thing).

I use EZcarrental because they have the shortest lines most of the time. they charge minimum premium for full size car. last car was a Chrysler 300. charge was under $100 for 3 days.

tell whomever you rent from that you want a light colored car.

carry an insurance card, just in case. also, bring a roll of quarters.

also, I never get whatever I sign up for, at any agency.
