Need for Speed Payback

This achievement requires you to reach level 50.

With the new update Ghost put out, this is a lot easier than before and if you're starting from scratch, you should earn this towards the end of your 100% completion. After I completed the story, all roaming racers, 3 starred all activities, and hit all billboards and found all the poker chips, I was at level 49.

If you've done all of this and are still in need of some levelling, you can go to any event you want, or one you found easiest, and re race it as I believe, after the update, you earn 275,000 rep for each win. What I did was go to the race "Fight Into the City", which is in the northern part of the map right at a gas station. This race takes about 2 minutes to do, full of straights, and once you're done you can simply fast travel back to the gas station and do the race again right away. This is what I did to get the last bit of rep I needed.

Also of note, I'm not too sure when it starts, but in the 40's, you're going to need about 1,000,000 rep to level up. With the new update you shouldn't need to grind too much if you're going for 100% completion, so I would recommend saving this as your last achievement once you've done everything else and grind it out with the race mentioned above.

By the time you've finished the story, beat all roaming racers, completed all activities and acquired all collectibles, you'll be around level 35. I repeated the first drift even "Drifting the Block" in the top left of the city area. With a well upgraded car you can finish the event in just over a minute and earn roughly 120k rep each time. The target score is only 18k and varies up to 60k but I have gotten 800k on this event. It's also a good event to grind money and speed cards. Make sure to always accept the bet, it'll either be to not come off road, finish under 85 seconds or hold a 650m drift. I used a LVL-399 Porsche 911 GT3 RS (991).

I got this at the end of Chapter 3. I have been grinding to make money to buy modifications/cards/cars. So I got this fairly early on. One quick and easy way to grind both money and rep is by doing the "Drifting the Block" event. I used a level 220 240Z. Always accept the side bets too for that extra bit of cash.
