DiRT

Getting this takes quite a bit a cash, and Dirt has a bit of a gotcha built-in. Once you win a race at any given difficulty level, the prize money drops for that level and all the ones below. So, If you do all the races at Amateur, you'll lose most of the money that could be won at Rookie and Clubman.

Working up through the difficulties on each race maximises your cash generating potential, this also gives you plenty of mileage towards the 1000 miles driven achieve.

Also, don't be afraid to have a crack at Pro Amateur and Professional on the Crossover races, you can get $75,000 for coming third and one of the guys is normally really slow, even on Pro. Again, once you have won a prize, the money drops. Even the second and third place prizes.

You can see what cars youve bought/ got left buy going to the garage. I got this buy racing tier 1 windy point hill climb driving the evo IX. I created a car set up setting the ride height to low and suspension to hard with downforce to 0.50 with gearing to long increasing the top speed to about 120 mph. on pro diff youll get £43750 (after youve won on pro once) for about 1:41 - 1:43 on average with first place faster than 1:46 once you get used to the course, its mostly straight i only braked for the two corners after time gates 2 and 3 and simply lifting off for the second to last corner otherwise full throttle. i found this the best way to get money and add a few hundered miles towards the Driven in excess of 1000 miles achievement.

I decided to add a car list with the cost of each vehicle for anyone that likes to have a list. All the costs are included as well, and the other solutions are awesome for methods to get enough money.

The way i did, is after completing your career, to go back to the easiest races, and do them on pro. in my case, i did all the races, like the rally-cross, the T1 raids, the crossovers, and the buggy races. with a little tuning of your vehicle you gain the extra edge. try getting third, then second, and if you can, go for first. if you do, you will win near a million credits for that race alone. then find another easy race to go for and repeat. i needed like 6 million, and got it in about 3 hours max. good luck guys! it seems hard, but just go for it and if you cant beat the AI, find an easier race.
