I managed to get proper shots of my cars now, so like
@SlipZtrEm, I'll use this opportunity to describe them.
Lamborghini Diablo: My favorite Lamborghini. At 1,000+ HP, it's my main car for races and time trials.
Porsche 911 (993): The 993 is my favorite generation of the 911, so I had to get it. Being the first car I bought, I used it for races, but after getting the Diablo, it's mostly used for drift events now.
SRT Viper: Other than being equipped with nitrous, it's completely stock. I use it exclusively for Outlaw stuff, so upgrades aren't necessary. (Not that it needs them anyway.
)
Ferrari F40: I loved the F40 Competizione in the older Forza games, so I wanted a similar car in NFS. I plan on upgrading the power to around 780 HP.
The car that is (temporarily) taking up my fifth slot is the NA MX-5. I drove it stock for a while for a challenge and then I moderately upgraded it to 292 HP. I'm going to fully upgrade later to see what it can do. It's also pretty amusing seeing the little Miata surrounded by supercars.
