Really want to give this 5 stars but the interior engine noise is unusually quiet compared to the rest of the car, even with respect to the default sound from Kunos. The starter motor and engine startup are loud and intense as they should be, but once you've got your foot on the accelerator the sound level dies away. The exterior views don't suffer from this issue. The quality of the mixing and sound samples themselves are excellent, however, with no clipping or strange hiccups.
