What happens towards the end of Roddy Doyle's novel, The Van?

Answer 1

The van gets the old heave-ho:

"Jimmy Rabbitte Sr. has been fired. He has no money, his family hasn’t money and he’s feeling useless. He is embarrassed because he can’t buy presents. The things changes when his friend Bimbo gets fired. Together they hang around and play games. They go to the pub and drink a lot, but both of them are unhappy.
Bimbo buys a van to feed the hungry people near by the pub and during football games. Jimmy Sr. and Bimbo work together on the van. The business of the two mates, and later including Jimmy’s daughter, is very good, they sell a lot. But one evening, Jimmy Sr. and Bimbo go to a pub and drink a lot. They talk with two women but only Bimbo has luck with a woman. Jimmy Sr. is jealous and angry. He hits Bimbo, but Bimbo doesn’t really bother.
When the two mates see each other again, Bimbo tells Jimmy Sr. that he doesn’t want to sell fifty-fifty anymore, but that he pays Jimmy Sr. salary. Jimmy Sr. doesn’t like this and they both are stressed. Than the health-inspector comes and nearly nothing is good. Jimmy Sr. and Bimbo have a fight and hit each other. At the end, after a few fights, they push the van into the water, because their friendship is more important than their company."

Hmmm, I wonder what book - or rather, movie - the first answerer wrote about?

It certainly wasn't "The Van."

Answer 2

Bobby feels confident that he can take over the town for the night and get the girl of his dreams. After a few run-in's with his co-workers Bobby tries to hook-in with several girls that he meets in a bar.

After trying to force sex on a girl and after making love to a girl who turns out to be a prostitute, Bobby tries for some bigger game and goes after a girl from his high school called Tina (played by Deborah White) and at the same time is drawn to the movies antagonist Dugan's girlfriend, Sally. After Jack falls for Tina's best friend Sue, Bobby is obligated to give up his wild games of chasing girls so he can be with just Tina, however Tina is not so hasty in going out with Bobby as she knows of his ways of using girls just for sex.

Bobby ignores his feelings and makes love with a very large girl called Bertha and after this relizes that he has to focus on just getting Tina, however he is once more interrupted along the course after he winds up having sex with Dugan's girl Sally, although it was only a one night stand, Tina is once more put off by Bobby. To prove that Bobby actually is really only interested in Tina, he kidnaps her and drives her to a secluded beach (after a long car chase with the police), and tells her that she is making him feel like he doesn't want to "play the game any more" of chasing after girls, she admits that she also feels like she wants to be with him, after making love, Bobby is set, but not before his boss Andy (played by Danny Devito) is in serious debt after a bet he made with some gangsters. To earn some extra money to pay back the money he lends Andy, Bobby drag races with Dugan, just before the race Bobby spices some things up by admitting to Dugan that he had slept with Sally and soon after calls Dugan a "turd". The flag is dropped and the race starts. Out of rage over what Bobby had earlier said, Dugan tries to drive Bobby off the road, unsuccessfully. Bobby flips over and rolls to the finishing line, however Dugan rams into a police vehicle (the same police that were chasing Bobby earlier) and fails to catch up.

Bobby wins the race, and the girl of his dreams.
