Sounds ok. But the interior sounds like its all the time in the tunnel. Theres also no wind effects included, no fly by sound, no custom shift effect is hearable in the exterior and interior sound. One tip, try to make a custom shift effect, that would increase the quality of your sound a lot. Also, im not really impressed with the exterior, the engine note is nothing special, or gives a motivation to drive this car only because of the sound. Try to look for samples on youtube, that dont have an tunnel effect.
