Some some beginner tips on fast XP/Money and prototype parts. [PC]

Probably not the best driver in this game but pretty good at the grind that it is, some tips I've figured out along the way.

PROTOTYPE PARTS

Do delivery missions as soon as possible to unlock prototype "day time" deliveries.
Once unlocked, there are now 3 types of delivery methods available, from morning, day and night. Keep rotating them until the morning and night delivery methods are in the south west of the map as these are the longest deliveries. Now you'll only get the daytime part deliveries to spawn in the city itself, with the longest possible delivery being just north of the city, which is still significantly quicker than the two that spawn in the south west. If morning and night deliveries are in the south west, the daytime one can never spawn there.

+tip, when doing deliveries, don't forget (down on the D pad) reset will always put you on the nearest ROAD. If you want to get on a road on the other side of a bollard then just press down on the D pad near it to save time. If you're high up and want to get onto a road down below you, instead of driving all the way down, just drop off the edge and hit reset before you slam into the ground. I'll shed a minute or two off runs sometimes doing this.

Waiting between delivery cooldown times, you can drive around finding blueprint trucks, over time you'll get an idea of where they typically spawn en masse, like the airstrip for example. I'll typically find 10+ whilst waiting for the cooldown to finish on the deliveries.

FAST XP/Money

Elite races do not have a direct "retry race" option when pausing. Group races do. Take advantage of completing groups before unlocking the elite races, by racing on hard mode. The XP drops after each race will make you level up much faster and subsequently gain more packs/money. You don't risk losing a "streak" during group races and it's much faster to reset if you make a mistake so they really aren't worth grinding through fast on easy mode. The best thing about them is the easy XP through hard mode.

If you want more money than you know what to do with, then build a C6 car as soon as possible, you can essentially do this for free if you do the prototype method forementioned. If you do the elite races in a C6 category, even on easy mode, you'll gain more money than you'll know what to do with by the last race.

Boring method for XP would be to turn traffic on and speed down the highway near missing traffic. I've also gained a lot of XP by joining Nürburgring multiplayer lobbies and just racing around with people in the same/similar classes as my car. Won't be nearly as fast but much more fun than just driving down the highway.
