Cars: Race-O-Rama

If you find any of the 9 races (there are 9, not 8 as the existing solution says) difficult and are struggling placing in the top 3, there is an easy solution:
- Exit the story mode and enter the Arcade mode, scroll over to Guido Kart, and choose any race that you haven't been able to defeat.
(NOTE: Races in the arcade mode will not be unlocked automatically, you still need to race at least once in the Story mode).
- At the vehicle selection screen, scroll over one place to Luigi (a small brown car). It has 4 wheels and will not lose traction and cause you to spin out as easily as Guido,
- You are certain to place in top3 using that car.

Arcade and Story races overlap, you can win some in one, some in the other and the achievement will still unlock.

This is the most frustrating achievement in the whole game. You need to finish in top3 in 8 Guido Kart races. They are extremely challenging due to to the insanely bad handling of your car. Furthermore, some walls seem to have powerful magnets built in - Guido runs into them without any controller input!

Some tips:
- in Race 2 it is possible to cut some corners: first, drive under the billboard; later turn left after the first "tunnel" and go straight through the desert, avoiding ~1/3 of the race distance
- in Race 8 (inside the mine) turn right soon after start and jump over both holes - you'll shave some precious seconds
- don't worry if you're doing really bad during the race - your opponents usually slow down during the last lap, it's possible to gain some places just before race finish
