If you get a shitty job done and they fuck the paint up, yes, it'll reduce the value. A good wrap job won't, just rip it off and get a 2 stage correction before you sell.
If I still had them, I'd still sell them for what I paid. I like more fast Supras more than I like money. I also want to see the B58s/A90s continue to have their own classes.
I bought a couple back when no one cared and everyone was afraid of the big bad Russians (which is a huge fucking joke), I sold them for what I paid for them, around ~$400 each. RIP that market.
It's definitely RaceCarThings™. I have meth in my car, but since it's really honestly a drag car that's occasionally driven on the street, rather than the reverse, I don't mind the complexity.
My tune, however, is not dependent on meth at all. Used for cooling only.
1. Stock oil filter is accessible on new gen. Old gen requires a little adapter that makes it accessible
2. No, any aftermarket will work with a coupler
2a. EOS does not change the throttle body
3. New version is a SLIGHTLY smaller core, but not by much
4. Nearly no temperature difference based...
