So you wanna start a mobile detailing gig, huh? Me too, man. Figured I'd save some cash washing my own car before charging others. Big mistake.

The Online Price Trap

First thing I did? Hopped online. Searched "pressure washer for car detailing". Saw these fancy machines listed for $150 bucks. Nice! Clicked through slick Amazon listings and big box store websites. Prices looked sweet. Like that Ryobi electric one - $159.99 on display. Almost clicked buy right there. Gut said wait.

Walking Into the Jungle

Decided to hit physical stores. Wanted to see these washers in person. Big mistake. Lowe's had the Ryobi model I saw online. Price tag? $219.99. Blinked hard. Asked the kid in the orange vest: "Why's it $60 more than your website?" He shrugged. "Online's different." Saw similar markups everywhere - HD, Northern Tool, even tractor supply places. Felt like walking into a car dealership.

The Spec Shocker

Started comparing specs. Thought "higher PSI must be better!" Saw a 3200 PSI monster washer. Only $299! Until this grizzly mechanic at the tool counter laughed when I told him. "You wanna strip paint off your Honda? Go ahead!" Explained car detailing needs LOW pressure - like 1200 to 1900 PSI max. My jaw hit the floor. Almost bought all wrong gear.

Dealer Games Begin

Found a "pro" detailing supply shop. Saw the CAT pressure washer I researched - $479 online. In-store? $549. Asked why. Manager grinned: "You need hose, nozzle kit, foam cannon right?" Showed the add-ons. Basic hose? $59. Nozzle kit? $89. That foam attachment I saw on YouTube? $129 extra. Suddenly my "$479" washer became $826 before tax.

The Back Alley Bargain

Got sick of being treated like a walking wallet. Found this grimy equipment rental place. Old guy smoking behind counter. Asked "Got any used units that won't blow my Camry's paint off?" He waved me to the back. Dirty NorthStar unit sitting there. 1400 PSI perfect for cars. Ran it right there - worked smooth. $275 cash. Threw in a crusty but working hose. When I demanded a proper receipt, he finally showed registration papers.

What I Actually Paid

• NorthStar washer (used): $275
• New detail nozzle set: $45
• Generic foam cannon (Amazon): $32
• 50ft hose replacement: $38
• Stress headache: Priceless

Don't be me. Online prices lie. Walk in ready for markup warfare. Check PSI twice. Bring cash for those backroom deals. And for God's sake - test everything before paying.
