impact of modern muscle cars on the old car market

I will say this about depreciation. We now what it means to any modern vehicle. My '95 cummins has 207,000 on the clock, and it was maybe depreciated totally out 10 yrs ago!?? But I will drive it till it or me dies. Not on my plate, nor do I need or want a new one. Yes it could be had for $56000.... crew cab, 4 x 4, Cummins, BUT.....
Back bout 1998 it was, I took a job that was 65 mi away, ONE way, I drove a $900 dart sport 318 car every day. It got what highway 15-18 mi per gal? I put some used tires on it once, a new timing chain and carb kit when I first got it. Never another dime. Never worried about it at work, nothing was gonna get it. Sold it after 2 yrs on the road every day for $2000. No depreciation , forget it sold at a small profit. Comfotable?? Not like a new vehicle. I could have drove the Cummins and wore it out pretty quick. Next vehicle was a '87 1/2 T. slant ram, 4 OD I bought for $2500, drove it couple yrs, never spent a dime on it and sold it for $3500. Was new truck more comfortable? yes. BUT......
Sometimes I have to wonder,??? All these people that restore these old cars and then whine about selling them at a lose.....maybe they should drive them enough to justify it al!!!??????????????//
