When I read the title of this post I just smiled. I kinda figured that you had done a burnout with the Mustang within a day or two of getting it.
As far as your question...Hell No ! I think from the first time that I did a burnout in a '69 charger, I was hooked. Every car that I have ever owned I have either done, or tried to do a burnout (those front wheel drive vehicles can be a bitch to do one in).
I love the month of August around here. Everyone is getting ready for the Woodward Dream Cruise and you see every make and model of car with the young and old driving them. We pull up a lawn chair on the side of the road and just sit and watch. It is funny watching the young guys trying to do a burnout (those are the ones you really need to watch out for cause they are all over the road). Now I will say that the older crowd does do a much better burn out. I think it is from all the years of practice.
Personally, I think a burnout is a must. Don't we have to make sure that everything is working properly ?
