There are just not enough Mopar people period.
There are a lot who are scared off by the price of going mopar.
Every motor head that has ever worked at the company I run(over 20 years now), have always said the same thing, ...man I love the look of (insert Classic 60's 70's mopar) but I can go 10s in my Fox body/Camaro for half the cost.
The ricers that have gone thru this revolving door here at work are a50/50 mix of , Man I'd love an old V8 Mopar, or Dude, man I mean I can run 12s and get 20MPG.
G3s are changing that to a point. 2 out of the 5 younglings here are running LXs body's , 1 Magnum , the other a 300. both high 11s low 12s the other is a WRK guy while the 2 spend their money on the family.
