In August, I'm travelling from the UK to the USA with my girlfriend. We've booked our flights: we're flying to Chicago (from London) and returning to London from Los Angeles.
Therefore, we need to hire a car from Chicago and drop it off in Los Angeles.
I've spent a lot of time researching prices. They vary wildly and it is often unclear if the prices include things such as one-way drop-off fees, excessive mileage fees, taxes, insurance, GPS, etc.
Also, I really don't know which type of car to hire. A convertible sounds great but might not be suitable in August due to the extreme heat. A small economy car is cheapest but would it be suitable for Route 66?
Any help and advice would be greatly appreciated.
