Yesterday I washed it completely outside and inside. Today I used a paint cleaner and wax to make it shine a little bit more.
Before:

After:

Definitely made a huge difference and fixed those marks on the bonnet. Still a lot of marks from what I think is some paint (Had it from before purchase), brake dust and asphalt.
Some more pictures:

Missing the front lip so will be looking for a replacement.

Left taillight fogged up, most likely be buying a replacement if it cannot be fixed.

Rims looking good after a good cleanup. Rust around the arches and doors, so will be working on that as well.

A few things to fix/change here, but looks much cleaner than it did before :grin:
So my checklist as of now is:
Rust around the arches and doors.
Small leak from the driver door, rubber is not covering the gap fully.
Finding a new front lip
Seat covers
New floor mats
Key remote not working, need new batteries or receiver is busted.
New gear nob
Left taillight
And some changes I would like to add possibly is:
Front splitter
Paiting the Front Calibers red
Tinting the taillights
Rear spoiler
K&N 57i Airfilter kit
Ford ST Speed stripes and badges
Possibly new rims
Steering wheel cover
New speakers
And at last maybe a double rear end exhaust pipe.
Going to a few stores tomorrow to see what they have available and get a few tips. Update to follow! If you guys also have a few ideas and tips, feel free to post it! Appreciate any feedback.
