Cant speak for everybody but i noticed that...if you take a 0/0/0 miles car, or basically a never been used before car, and use it in a offline race or online race, it takes chassis damage. Now i dont know if you crash or not makes a difference or how much it does. But i do no that every stock car i have used or tested takes chassis damage. I also do not know if when it takes damage
Contact will get you chassis damage, even a slight gash or trade paint. But, even if you don't hit anything while driving it, as long as you drive the car really hard and push it to the limits, it will start taking chassis damage, even the slightest. I've tested this before, when I was farming money through the 650PP Seasonals on Nurburgring. I had some races when I didn't hit any of the opponents or the side walls of the track, but most of the time I still get chassis damage.
does the price to fix it change based on how much damage it takes i havent tested it. I have tested that if the milelage change's it takes damage. I also have not noticed a difference in handling or breaking after a stock car takes damage
No, the price is fixed on every car. The price depends on the price tag of the car. Most of the time the cost of the Chassis Maintenance is half the price of the car. For cars that are worth 1Million credits and higher, Chassis Maintenance is at a fixed price of 500,000Cr.
in a nut shell thats basically what i said. if the mile counter moves it takes chassis damage.
If you drive a new car or a rebuilt car for a few miles without contact, you'd still have a fresh chassis. If you get more miles on it and still without contact, only then will you get damage.
What I havent tested is it the same price to restore it if you put a mile on it without crashing or a mile on it and do crash it. I have tested for sure two cars that if crashed or in my case rolled cost almost as much as the car does new,...the 08 civic type r and the lexus LFA.
As I've said, the price is fixed. Without or without contact, sligh dents or a fully-busted chassis (can be done with a rollover and your car lands upside-down), the price to fix the chassis only depends on the price tag of the car you're using.
I"ve always wondered about this... Honestly I'm still wondering... Does it help the car or not?
Yes it does. Try to barrel-roll a car using the Trial Mountain course's last corner (hopefully the car lands on the ground upside-down). Once the car resets, try driving it. You can feel the chassis is busted, the car is "not pleasant" to drive anymore.

Buying Chassis Maintenance is a quick fix for this. 👍
