Today, I've done a lot of upgrades to my Nissan.
First of all, I removed and sold suspensions, brake discs, springs, interior and rusty parts ( doors, trunk, rear bumper, etc. ). I sold them for 350 V$.
Spoiler: 
After selling the rusty and unnecessary parts, I spoke to one of my friends - who is a painter - to paint my car. The paint shop cost me 750 V$.
Spoiler: 
After I painted the car, we ( my girlfriend, best friend and me ) searched for new garages and we found one in Bucharest ( the captial of Romania ).
Spoiler: 
It's a pretty big garage, where I cand run and work as it should.
After we set up in our new garage, I've searched on internet new running gear kit. I found a GReddy Type S spring and shock absorber kit. It was second-hand, but the owner never used it, so I bought it with 1,600 V$. The suspensions cost me 1,000 V$, they're new.
After I ordered the GReddy kit, I also searched for new brake discs, so I found some Brembo Big Brake Kit for 1,400 V$. They're new too.
Spoiler: 
Like everything to be complete, I ordered new rims and tires for 1,750 V$.
Spoiler: 
The wheels are some ISS Forged GT7 and the tires are Dunlop Direzza.
Spoiler:
14,400 V$ + 100 V$ = 14,500 V$ ( selling running gear )
14,500 V$ + 250 V$ = 14,750 V$ ( selling rusty parts )
14,750 V$ - 750 V$ = 14,000 V$ ( respray )
14,000 V$ - 1,000 V$ = 13,000 V$ ( suspensions )
13,000 V$ - 1,600 V$ = 11,400 V$ ( GReddy kit )
11,400 V$ - 1,400 V$ = 10,000 V$ ( Brembo Big Brake Kit )
10,000 V$ - 1,750 V$ = 8,250 V$ ( ISS Forged GT7 rims and Dunlop Direzza tires )
