Beautiful car!
My observations and comments are mostly in the area of creative options to consider. They're based on the guiding principal that anything in a photo that doesn't contribute to the story of the image or subject, is a distraction to be eliminated.
First, I wouldn't photograph the car in front of your house. It's not a setting that focuses the viewer's attention on the car and it's most attractive attributes. You want the viewer's gaze immediately drawn to the car. The setting should contribute to the vehicle's story or, at worst, be brutal.
Is there a track or road course in the area where you could make the photos? A dark asphalt road surface will set off the car better than a light gray concrete surface. Positioning the car on a bank, in a turn - especially an undulating curve on a road course - would add a dynamic setting that contributes to communicating the personality of the vehicle.
I'd also wait for a cloudy day when the sky will act like a giant soft box. Soft even lighting will lighten shadows, even out the illumination, and avoid overblown highlights. It's a quality of light that will showcase the beauty and elegance of the vehicle.
By choosing a better location and better quality light, you can call attention to two of the most important qualities that will attract buyers... its power & speed and the car's beauty.
Good luck with the sale.
