Hindsight
Looking back over the past month it feels like I have put in a lot of work for this and dealt with many issues especially shader related ones. Not being a vehicle person I'm pretty happy with the outcome despite the barn not quite turning out how I imagined.
The wheels could have been less tris and there could have been more decals and livery on the car as it seems pretty bland towards the rear. Making the lights, both back and front, emissive and on for the final shot could have been a nice oppurtunity for interesting lighting situations. Also alpha-masking the windows slightly to make them tinted but able to show the silhouette of the seats and steering wheel would've been nice and added depth to the vehicle.
Overall I enjoyed working on this for the most part, all seemed to go pretty smoothly until the shaders and although that was a headache I feel a lot better for doing it.
Here's a final sendoff for my vehicle:
