There is AA there are support groups for Drugs gambling etc... yet there is nothing for car addictions.
I feel you brother.
I have so much invested in my RX7 is just stupid. But it brings me so much joy.
In a way I had to get rid of my 911 or else I was going to spend thousands I did not have ready on suspension upgrades.
I was just thinking today, my next fun car will be a Factory Five Cobra while trying to convince the wife she needs a JCW MINI Cooper S or a BMW 5 Series...... I have issues as well.
