Looks clean. You should remove the for sale yard sign from behind the front desk though...
@TheMagicTractor BTW, the code just says FELTZER, not feltzer2.
@TheMagicTractor He probably has those vehicles modified in his game. Assuming that you created a backup of your handling.meta, open his file with notepad and just copy the section for the feltzer2. Then in your original handling.meta file replace the feltzer2 code with what you just copied from his file. This will ensure your other vehicles remain unmodified and will only change handling for the Supra.
