So let me drop this on you. A 20 year old car say person x enjoys has 250,000kms on it. Over 20 years it's for sure sagged almost an inch (trust me and I'm not going to get into an argument on if this is possible as it fully is ask any other mechanic) so person x is in said scenario about killing someone. Insurance now has the grounds to not cover them as that could be viewed as non disclosure lowering even if you argue it isnt? Seems rather ridiculous when you're talking an inch at most doesn't it? my car is 6 inches and I get it but an inch they aren't going to argue with you.
That doesn't require aftermarket parts/accessories. That's why they always ask if you've got any aftermarket parts or accessories.
