MP4-25 is basically the second best car in the game. Turn that spot into the Sagaris or MP4/8 and replace Trion because it's terrible. Also, 675LT does not take a long time to buy and pro:

DAY 1:I started with 6 V8 engines. Bought 675LT.

DAY 2: Farmed for upgrades. Got to 4545 MAX. Used a bunch of A class parts and V8 engines.

DAY 3: I got another 4 engines. Used.

DAY 4: I got another 3 engines. Farmed for upgrades.

DAY 5: Stuck.

DAY 6: 2 V8 engines, 1 to go.

DAY 7-9: Nothing happened.

DAY 10: Last V8 engine, car PRO'd.

I may have struck gold or something, but I feel like this is pretty average of how long it takes to PRO.
