The Escudo is definately worth buying because you can get it over 1800hp and it will slaughter your opponent in ALL of the rally races. The bad news is that it is only good on rally tracks. Also, with the right settings you can take it over 500 mph!! An easy way to get money for this car is to race the European Championship in Amature mode and get all golds in the first 4 races. Then save your game. Exit out of the 5th race and you will automatically win the series. If you are awarded the Vertigo race car you can sell it for 300,000 credits. If not, reload the game until you do get it. Doing his can get you around 300,000 credits per hour. Have fun.
