Booked a Mustang last year at either JKK or IAD - cannot remember-with Avis. The car ws there but on examination the wife refused to travel with a suitcase on her lap because the boot was to small to accomodate all her baggage. So we ended up with a six door 4x4 which had all her luggage sloshing around in the back. Mind you, it was snowing in Maine so we were happy not to have the Mustang at the end of the day.
