I want my car to be broken, 173,000 miles?

I have mk1 Ford Focus 2004 automatic, with 173,000 miles, how long will it take until it breaks completely? I don't like it, I have had it for one year now, it's my first car since 17 and now am 19 it's coming up to two years and am at college can't afford a new car please help me, until it breaks then I can buy a new car from my mum she will pay for it

You have it one year, from when you were 17 until you're 19? Maths not your strong point.
Neither is appreciation for what you have.
Cars can run for thousands of miles, so it probably will still be running when you're 45.
If you want to sabotage it, disconnect the bottom water pipe, let all the water run out then refit it. Keep running it until the pistons warp under the heat.

Poor lots of small rocks in where the oil goes. That ought to help.

So your solution is to cause your mother financial hardship by having to purchase a car for you. That's absolutely priceless, Mate.

How about everyone who wants to spank this kid give me a thumbs up.

And what would your mommy think if she knew you were trying to intentionally break your car just so she will buy you a new one… Perhaps you should be grateful that you have a car at all, because if you were MY kid, with THAT attitude, you'd still be riding a bicycle instead of driving.

Get it serviced regularly. The mechanics will find something

Roll it off a cliff.

You think Mummy's going to buy you a "new" car? You'll get another old heap that runs.
