This is copied and pasted from a guy who is the on GR Corolla forum as I also posted a thread over there about the comical fact of this thread i.e FiST costing more to insure than a brand new car. I repost this because it offers a lot of insight how the insurance companies do things and why it also shows why if you own a FiST now no matter where you are you kinda get hosed on Insurance even if you think it’s cheap. It’s more than other comparable cars.
I should add I still love my FiST and really would rather not sell it but for what I have to pay for Insurance on it living where I live there is a big ? At this point.

Source: I worked as an underwriter + tech liaison in the high risk division of one of the biggest
insurance companies in the US for almost 6 years. Due to the nature of what I was doing I learned the entire underwriting process and worked directly with auto underwriters for much of that time in addition to P&C. So I am at least, a little educated on the industry. This is not intended to be a full explanation on how risk is calculated and how policies are written so if you want to get into a pedantic "yeah, but" argument go get riled up on someone else.
Why did I call it dangerous? The Fiesta ST is, in insurance terms, a dangerous platform. Yes, absolutely this was the case. But not physical danger. Dangerous as in, high risk for costing the insurer money.
Why is this true? The highest value of at fault claims, large claims, property and liability claims for the Fiesta during it's production run were for the Fiesta ST by quite a bit.. I do not recall the actual numbers as it was a few years ago before I got the hell out of the insurance industry and I was not about to save data like that on my personal machines.
Again, I am not referring in any way to the actual physical safety of the Fiesta platform nor am I debating if it was a well built car, it was absolutely a great platform for a long time. I am referring only to the risk related to writing a policy on the ST itself. Why do I even know this? In 2018 I was debating the FiST vs FoST for months before finally settling on the Focus. So, due to my job at the time, I had access to information like this. Being a gigantic nerd, I researched it. Who knew it would come up on a random car forum shortly after getting rid of that Focus.
(Unrelated Note: I should have bought the FiST, got the Focus because it was bigger and the wife didn't like how small the Fiesta m,y buddy had was. But she also hated the Focus, oh well. The first thing she said when she sat in the GRC was literally " I never liked the focus". Not sure I will ever truly forgive ford for discontinuing the FiST/FoST+RS in the US. At some point, there will be a FiST project in the garage.)
The Ford performance modding community and modding communities in general for popular brands are a well known factor for good auto underwriters. Claims agent, phone customer service/sales people, sales people in the small branches etc, they don't know much about anything. However, it is an underwriters job to understand the industry they write policies for. They do absolutely take things like this into account. There has been a demonstrable lag time when a new "performance" platform or model launches before enough historical claim data is available that they are treated mostly like the existing models. However, in my experience 3-4 (ish) model years in, that data tends to ramp the policy cost if the claim data supports it, which in cars like these, usually happens. Because let's be honest, it is impossible to behave yourself in a car as fun as either a FiST or a GRC.
The 240sx stopped production in '98, my 250+hp death trap '97 civic hatchback cost me like 18$/month to insure in the late 90s/early 2000s. That no longer really matters because the rules are no longer the same. While slow to adapt (so.. god damn slow), the insurance industry did adapt to the new data being tracked and made available to take a lot more into account than they used to. Simply put, because there is more information immediately available and so much more technology behind how insurance is written the rules we once operated under, no longer apply. We got away with way more back then than we do now. That's not a debatable fact, as much as everyone who was doing gearhead things w/ cars in those days and before would prefer it was.
It's not the mods themselves that impact policy cost as it is the existence of huge, verifiable modding communities and their inferred impact on at fault claims. Acting like Ford does not have an absolutely massive modding community is silly. Especially when talking about one of the most adaptable littler rippers that ever existed.
FiST facts: The car is discontinued, oem parts become harder to find over time and thus, more expensive. This is not incorrect. It has less safety features than the GRC, also not wrong.
It would absolutely not shock me to see GRC premiums go up at least marginally beyond normal insurance company greed somewhere around mid model year 3 as policies start to renew during that cycle.
TLDR: Auto Insurance providers are predatory shitlords and absolutely hold a car being a performance version of a normal car against us, once they remove head from collective ass and realize it exists after a few years.”
