Biddle "nailed it" I hope he leaves the "non-Ford" images on here to reinforce his point.
You can do everything right 100% of the time and some teenager updating their Facebook page can change your life in an instant of distraction.
You brought up two things, reliability and safety, I'm a rarity in that I can give you "real-world" personal experience with both.
I can tell you a vintage car can be as reliable as you have the skills to make and maintain it. This fastback Mustang made the 3 hour run from Tidewater, Virginia to Southern Maryland (where I worked during the week) EVERY weekend for two years at 65 mph in the late 90's. Never once, let me down or gave me a problem; it was also my daily driver in Maryland while I worked there. However, original and even good repro
parts are harder to get now and a water pump or other failure might take you days or weeks to resolve, not good for a daily driver.
Safety is an entirely different issue, these cars have no crush zones, collision, computer "nannies". airbags, ABS brakes, shoulder harnesses, side impact protection, collapsible steering columns and on and on. And now, with distracted drivers, texting and possibly under the influence or just plain aggressive - its not the same world when I commutted. Trust me on this, I have first hand expereince, my 63 Corvette in 2016. Aggressive, uninsured driver on a sunny, summer Sunday afternoon in an Escalade pulled right out in front of me. $65,000 and 18 months to repair it, I got knocked out and if it were any worse I wouldn't be typing this. My meticulous attention to maintenance (like the original drum brakes and lap seatbelts) saved my life; the perfectly opreating brakes hauling me down from 40 mph to a survivable speed before impact.
Others will disagree but
I wouldn't recommend a vintage car for a dialy driver.... They are great weekend crusiers and a wonderful hobby though.
A word on classic car insurance, nearly all policies provide a low premium because risk is reduced as the car is driven a limited number of miles and usually to car events. They also provide "agreed value" meaning you and the insurance company determina a value for damage repairs/replacement - this Corvette had a $95,000 policy. A Daily Driver policy will be substantially more expensive and may only be "stated value" - meaning, if the car is wrecked, it would most likley be totalled and the compensation would be for a 60 year old, used car and next to nothing. Do your homework on this.
Just so people don't worry too much, the Corvette was repaired by an expert with 50 year sin the biz and sold last June to a South African collector for a substantial sum.
