Wow funny glitch?

[Aphelion]

I was busy tuning a 370z, putting body parts on it, when gt5's save data corrupted! luckily it had a backup, at around the time i bought the z, so it was stock again. HOWEVER, when i went into the tuning options, the car clearly has a wing and a front splitter, but when i drive it, it dosnt! This is just a glitch... right???

That's a "normal glitch", the thumbnail of the car isn't stored with your save data, but the GT5 data. You can update the thumbnail again in your garage, press triangle on the car and select "create thumbnail".
Going in and out of GT Auto with your car again will also update the thumbnail.
