Need for Speed Unbound

This achievement requires you to complete Qualifier 2 in story mode.

This qualifier takes place after your second week in story mode and has two requirements:

-$50,000 Buy In
-A+ Class Car

This means you need to have $50,000 cash and an A+ Class car by the end of Friday evening. This shouldn't prove too daunting as there are many opportunities to earn cash throughout the week. Obviously keep an eye on your heat and be smart about the races you choose to do. Only go for the big money races. Don't waste time with small payouts or trying to complete every event in a day or night.

It's also important to keep in mind you want to do the races that have the biggest difference between the buy in and the reward, not the races with the biggest reward. This is because your buy in is included in the reward. For example, it's better to do a race that has a buy in of $4000 and a payout of $16,000 over a race that has a buy in of $10,000 and a payout of $20,000 since you're +$12,000 in the first scenario but only +$10,000 in the second scenario.

Another tip is I always tried to stay below Heat 3 going into the night as the night events pay out more than the ones during the day, and as soon as I hit Heat 5 I'd make my way to the garage.

Anyways, once you reach the qualifier, just race through the set of races as normal. Once you finish the qualifier you'll get your achievement, $100,000 and a custom Crown Victoria.
