Where are the a bodies going

I don't know, now doesn't seem to be a horrible time to grow up in based on the huge HP and drivability that is available from the dealership.

Gone are the days were a used musclecar could be had for cheap and a couple of speed parts slapped on it to make it faster than anything coming off the showroom floor. The only thing an older musclecar has going for it now is style because it get's really expensive to try and keep up with most performance cars built in the last 10 years. And by "keep up" I mean, idle in traffic without overheating, comfortable to drive, functional AC/cruise/PS/PB/PW/radio, better mileage as well as just flat speed.

To be fair, the new muscle used car values are way out of line right now. So it's not exactly easy any where. But pretty sure you could buy a first gen Jeep SRT8, dropped a SC on it and run away from most cars on this forum for less than a restored 340 Duster would cost you. Maybe it doesn't fit your style, but for a 30 something that didn't grow up working at a gas station and seeing the old musclecars come and go, bet it fit's his/her style just fine.
A jeep isnt a muscle car...neither is a pickup truck with super bee stripes around the back. True modern muscle is out of reach for most young people money wise new or used. Im talking the combination of performance and style. I got into a conversation with a nitwit in a bar. i was talking about my Fox body to a friend and he chimed in about his Nissan . I said "nobody wants to hear about your Nissan" it didn't matter if it had 300 hp to my stock foxs 225...id keep up with it at top end because of power to weight ratio and torque at RPM...
