What I also was trying to say the first time around was the amount of care all these machines take can consume all your time when your driving season is short.
On the other hand if cars are your business like Leno, he has a lot of guys helping him out so he can enjoy one car per day. Oh, did I mention that he has to be a sustainer for all those guys, and some for life, so you end up with employees at work, employees at home and it goes on. Your choices may vary but it's all time management. Where is El Guapo when I need him.
