Excuse me sir - I'm going to have to ask you to stop jacking my style.
I agree with pretty much everything you said. I kept my Evo X because I wanted to have something to use in bad weather, and because it's modded and will be my modding toy for the nearish future. The interior comparison is night and day (my evo was an 08 with like 0 interior options lol).
Edit: also 6'4" here. Wish the seat in the vette was about 1-1.5 inches lower!
Sweet cars, LOL Biased...
I wish I could justify keeping the Evo. Sadly I can barely justify having a Corvette. I have a more pedestrian Hyundai for inclement weather days.
Honestly I don't think the Evo interior has changed much since 08. The only feature my 2013 has is a aluminum shift know and handbrake lever. Which are super cold in the winter and will burn you in the summer, lol sweet. Oh I have some blue LED accent lights that were like a $300 option...
It is interesting that you would like more headroom and I want more legroom. I have a 36" inseam for what it is worth and no issue with headroom. It sounds like 6'4" is just about the max height for the car. Maybe 6'5" if the torso length to leg length was perfect.
As for the endless automatic vs manual debate...
I prefer traditional automatics for big torquey engines. Manual transmission for smaller engines and or turbos.
