XDC customers who decide to rent an exotic vehicle from us for a week or longer will receive the opportunity to return their car and trade it in for a different one, whenever they want! Clients can upgrade to a different vehicle at a greater rental cost (clients will be responsible to pay the difference if any) or pick a vehicle of equal or lesser value at no cost to them whatsoever! Please note some restrictions do apply, such as vehicle availability and additional costs for upgrades.
