Yes your right Bill, sorry. When I mean commercial, I really do mean retail.
As far as racing for years. I do have cars that we have been racing hard for years. The most immediate one that comes to mind is the A1GP cars. I still race the one I raced last year. Of the six I have and raced all but one still races like it did last summer. Of course, when I mean for years I don't literally mean every time there is a race I race these cars. More of a seasonal thing. In other words, the cars we have raced for a season still are raceable for another season. Heck I rarely change out the brushes and rarely the motors. Sure wings and mirrors break off but the cars still run great. And remember before we had Marshall Field we had the Underground Raceway and Byron and I raced for years 3 or 4 times a week for hours at a time there.
I have heard comments from others too about how they race all season and have never even oiled their cars.
Now this class we are racing is extreme and the cars take a hell of lot of pounding. But my Ferrari will still be running strong way past the end of the season. My other car got trashed pretty good and I have to replace the chassis. That only cost about $18. In the 1/24 scale world of Paser, I have seen cars come off thetrack with far more expensive damage. Heck the tires need replacing almost every race and they aren't cheap. Not to mention motors, brushes and gears that go out all the time. So in a comparison with that world, the 1/32 retail stuff holds up pretty damn good, at least in my experience. And I can only relate my experience to people. If compared to the amount of race time I have put on these cars and the amount of race time put on 1/24 scale Paser racing, I would have to say I have had really good longivity with the 1/32 scale. Much less expensive too.
Just my 2 cents worth of observation. Maybe I'm just lucky.
Take care,
