To whoever was stuck on the last race about 3 years ago, it's not hard at all. I beat it regularly for money. I've even beat it with an RX-7. In fact I've taken it with all three initial cars, the Eclipse, the Mustang, the MR2, and the DB9. I'm going for beating it with every car, and am customizing an Audi TT for the purpose now.
You just have to watch out for traffic, and for collisions with enemy cars at the end. If they get off better than you, you're doomed.
