Will I Fit---Confortably?

It's new car-buying time for me, and I've had my eye on the 2018 Honda Accord EX-L 2.0T with navigation. I've never owned a Honda before, so I've been performing my due diligence, researching everything about the car that I can find. Despite my intense efforts, though, there's one definitive answer that's been eluding me. So it occurred to me to do what the old Packard advertisement recommended: "Ask the man who owns one."

I'm six-foot-three, legs and torso in proportion (so no short legs, long torso, or vice versa), and large build (250 lbs.). Will I fit comfortably in a 2018 Accord? Particularly with reference to headroom.

I've looked at various sites which list the driver's headroom specs and they vary between 37.5 in. and 39.5 in, and never does that tell me if that's with the seat in the normal position, or lowered to its lowest point. Legroom specs have been consistent at 42 in. I've been driving a 2014 Nissan Altima for years---it has a 45-in. legroom and I don't have to move my seat all the way back---so I don't know if 42 in. is good for me or not. I've read one professional reviewer of the car (6'5") and one consumer reviewer (about a 6'2" passenger) remark that their knees scraped the underside of the dashboards. That set off an alarm bell.

There are three dealerships which has this trim of the Accord in the colour I want, but none of them are close to me. I don't mind driving seventy or ninety miles to buy a car, but I don't want to make the trip just to find I cannot sit in it comfortably.

Everything else about this car is attractive; in fact, it's at the top of my short list. But I really need to know how it fits on me.

Much obliged to any of you who can help with some information!
