Agreed. The 4th gen cars sat you wayyy too low and there's no hope of seeing anything past the edge of the dash. I could never get comfortable in them.
I've never owned a foxbody but the SN cars I'm very comfortable in. I'm not super tall, I know several of my 5' 10" buddies could never get comfortable in my SN's but they were ok in Foxbodies
The sloped hood and big windshield must play tricks on you. The 3rd and 4th gen cars actually share a lot of proportions and sizes, other than the front clip and roofline. Front and rear seats both swap between generations. The floor pan is roughly similar and the entire rear suspension is the same. People have actually used 4th gen door panels and dashes in 3rd gens because they are so similar in size. But anyway, I'm not actually sure why I like driving a 3rd gen better. I should like the 4th gen just as much, but I don't.
I haven't spent much time in the fox bodies. I just remember them being cheap and basic feeling, but overall comfortable I guess. It's the later ones that I'm uncomfortable in. Especially the manual trans... shifter placement is terrible, imho.
