But her husband struggled to remove the plastic casing, and when he used a screwdriver to pry it off, it shattered.
What came next was even worse. Her Nissan dealer wanted $250 to order a new one.

Musall figured "10 bucks, we'd be done." "But apparently," she said, "it's not a do-it-yourself thing if you don't know
what you're doing."

Car owners looking to trim expenses are sidestepping the mechanic and plunging into their own repairs.
Or trying to, anyway. Their efforts can backfire, costing more in the end and creating do-it-yourself horror stories.

Mechanics say they've seen it all in recent months, including incorrectly applied brake pads and antifreeze
poured into engines.

A lot of people, they're in dire straits, They try to do this stuff at home in their driveway.

The results can be frustrating, and sometimes outright dangerous.

Beth Riggs took her Chevy Trailblazer SUV to a car-savvy neighbor nearby who charged $500 to replace her
front and back brakes, far less than the going rates at nearby repair shops.

Later, on a highway ramp, her car suddenly froze up and pulled to the side of the road. The problem? Riggs says
her neighbor neglected to put a certain part on a bolt of the wheels, setting off a chain reaction that caused the tires to lock up.

The car had to be towed, and Riggs ended up paying an additional $400 to have it fixed at a suburban Cincinnati auto shop.

While well-intentioned, many people forget that today's cars are vastly more complicated than models made just years ago.
Most are so computer-controlled that owners can't spot problems without access to specific tools and data programs.

Even jobs that were once simple, such as changing the oil, can take hours to complete now.

They're not able to do nearly the work that they used to do — it's even going beyond the heads of a lot of technicians
who aren't keeping up-to-date.

Even so, some car owners remain undeterred. On Yahoo, queries for the terms "car repairs" and "salvage auto parts"
are up 77% and 99% respectively in just the past month, according to the site's data.

Other car repair search terms remain at three-year highs, reflecting a renewal of the good old American independent spirit.

That doesn't mean repairs come easily. One man tried to change the oil on his Mercedes-Benz sedan — and wound up
with it all over his face, a situation he likened to an episode of "I Love Lucy."
He also struck out replacing spark plugs on his BMW.

Auto shops say there's an easy way to save money: Just be upfront about the repairs you've tried at home.
Most do-it-yourselfers, perhaps out of sheer embarrassment, play coy when mechanics start asking questions about
what went wrong with the car. Rather than saving themselves time and money by telling the whole story, they'll just say,
"This doesn't seem to be working" without going into the details of what they've already done to destroy the whole mechanism.

To piece together what went wrong, mechanics typically have to start asking questions, and lots of them.

People who try the at-home tinkering are usually out of work or low on cash. Many of them are men who work as contractors
or handymen in another trade and think they can apply those skills to car repair.

It's those people who have that mindset, "Hey I can fix this, I can fix that,". "Bob the Builder type people."

Musall, with the broken taillight, says she's learned her lesson.
Her husband won't be laying his hands on the car anytime soon.

"It's all fixed," she said, "and he's not going to do any more car repairs."
