I don't have a friend with a Ferrari, but I do have a friend with a Boxter. When I took him flying he drove me to the airport and scared the s*it out of me. As I am a firm believer in fairness, once airborne, I scared the s*it out of him
On a serious note...I wouldn't ask for money from my mates, unless if they approached me for a trip to the channel islands or something special. Even then I'd probably pay the costs [and not tell them about fuel drawback

] and they'd pay for lunch / beer / women etc.
