I took a look out of curiosity and while it isn’t too bad stats-wise, this car just didn’t have the right approach for this csr round which is why it was binned quickly imo. This body is a small sports car while the people were looking at mostly luxury sedans and SUVs. Using the Aston Martin body is already on the small side for this round and it doesn’t matter how luxurious it is if the passengers are cramped.
Looking at the stats, comfort, reliability, and safety are a kinda low but drivability, fuel eco, and price are good. Using the engine and body you did seems like an uphill battle from the start but it looks like you put in a lot of effort to make it work.
The engine is an odd choice. A 6L V12 is very luxurious, but kinda crazy to stuff into something this small. Its like a mini Viper 
. Direct Acting OHC is outdated by 2007, and you should use forged/lightweight forged internals for a higher performance engine like this. Generally you should only use titanium and billet if you have to. You tuned for fuel eco with a very low cam profile and used 91 RON instead of 95 RON for CSR. If you want good fuel economy, smaller engines are the way to go. 25.7 mpg is more than you need anyway. When you use AWD, its usually best to try and use the same tire widths front and back to save a lot of material and service costs. Brakes are expensive, just use what you need.
Design wise, you put more effort into this than many who got binned from the looks of it. Its good you are laying out shapes with vents to help build up lights and you are making use of layering. I agree with Mr. Computah and I think the main issue is that the shapes of many of the fixtures don’t flow well together and is out of proportion.
For example, you have very boxy lights pushed up against a very rounded grill.
Also keep an eye on proportions. In ^ this case, the headlight could be a bit smaller to line up with the width of the vent below and moved up a little to line up with the top of the grill.
Following the lines of the body help make a cohesive design too. Here you want to keep the taillights off of the bumper to keep it from bending in weird ways and looking pasted on. Also it looks sad compared to the front. Don’t be afraid to use similar light shapes for both the front and back to tie the two together.
Also proportion wise, those exhausts are huge.
I see you wanted more of fastback shape with the cabin, but unfortunately morphs are limited in what they can do. I would just use the fastback body variant here.
Last thing, I’d stick a badge or brand name somewhere. Doesn’t have to stand out or anything but its like an artist signature. It lets people know what it is and who built it 
I messed around with the design for a bit and this is what I came up with for the front and the side. I tried to stay somewhat close to the original idea with the big side vent and lower fascia. This is by no means perfect or the only way to do it, but it may help you get some ideas.
