There is a very specific kind of satisfaction that comes from proving the internet wrong, and Tim from BackYardBoyz on TikTok just served up a masterclass in it. The Washington-state car flipper recently went viral after purchasing what most people would describe as a rolling disaster: a BMW E46 convertible with a knocking engine, mold blossoming across the interior, and enough standing water in the trunk to qualify as a small pond. The price tag? A remarkably optimistic $2,100 from Facebook Marketplace.
As you might expect, the internet had opinions. About 1,000 of them, by Tim’s own count, and none of them particularly kind. The comments flooded in fast, calling the buy a mistake, a money pit, and worse. For most people, that kind of pile-on would sting. For Tim, it was apparently just noise, because while others were typing, he was already working.
Tim, who goes by @bybtim and has built a following of more than 357,000 on TikTok, posted the video this past Tuesday. Within days it had racked up over 2.7 million views, because what followed the mockery was the kind of reveal that makes you want to close every tab you have open and go learn a useful skill. The car, once pressure washed and given a basic mechanical fix, turned out to be one of the cleanest late-model E46s many viewers say they have ever laid eyes on.
What started as a joke at Tim’s expense quickly flipped into a case study on how to spot value where others only see problems. It is the kind of story that travels fast online, not just because of the car or the dollar amount, but because everyone loves watching someone eat their words with a side of a clean German convertible.
What Exactly Is a BMW E46, and Why Does It Matter?
For the uninitiated, the BMW E46 is the fourth-generation 3 Series, produced between 1997 and 2006. It came in several body styles including sedan, coupe, convertible, and estate, and it sold over 3.2 million units worldwide, making it the best-selling 3 Series in BMW history. That kind of production volume means parts are plentiful and the ownership community is massive, which also means knowledgeable buyers have been snapping up clean examples for years.
The E46 has quietly become a collector’s darling. The M3 version, widely considered one of the greatest driver’s cars of its era, has a median auction price hovering around $32,550, with top examples pushing past $117,000. But even a standard non-M variant like the 330Ci convertible that Tim bought carries a median trade value of around $14,175 when it is in decent condition. That number makes Tim’s $2,100 entry point look less like a gamble and more like a calculated read on what other buyers were too squeamish to look past.
The platform also has a known quirk that became central to the video’s drama. E46 convertibles have two drainage channels routed beneath the soft top mechanism designed to carry water safely away from the cabin. Over time, those channels clog with leaves and deteriorating material, which sends water straight into the trunk instead. Tim found exactly this when he opened the trunk and discovered standing water in the spare tire well and the battery tray.
The Fix That Divided the Comments Section

Tim’s solution to the water problem was simple: he drilled small drain holes in the affected areas and moved on. The internet, predictably, had thoughts about that too.
Several commenters pointed out that the car actually comes with factory rubber drain grommets in those compartments that can simply be pulled out to let water escape without putting new holes in the metal. Others warned that drilled holes create entry points for rust, which is not a small concern on a car that is already dealing with water intrusion. One commenter laid out the proper fix, explaining that clearing the original clogged drain channels takes care of the root cause rather than just moving the problem around.
To Tim’s credit, he was transparent about not finding the grommets, and the broader point stands: the water issue on these cars is well-documented and entirely fixable. It is not rot, it is not structural damage. It is a clogged drain that has been sending owners to E46 forums for going on two decades.
The mechanical side of things was even more straightforward. The engine knock that scared off most buyers? A water pump replacement. Tim says he knew that before he ever handed over the cash, which is the entire foundation of the buy. The knock sounded catastrophic to someone scrolling past a listing. To someone who actually knows E46s, it was a repair estimate, not a dealbreaker.
The Reveal and What It Is Now Worth
After replacing the water pump and running the car through a pressure wash followed by about 20 to 30 minutes at a self-serve car wash, Tim took it to what he called his go-to reveal spot and let the car speak for itself. No polishing. No buffing. No detailing products beyond water.
The result was a car that looked, in Tim’s own words, like a show car. Commenters agreed, with many saying they had never seen an E46 in that kind of condition. One summed it up neatly: “116k miles? Convertible? $2,100? That’s a hell of a deal.”
Tim estimates the car is now worth somewhere between $4,500 and $5,000, more than doubling his investment before any cosmetic work is done. He is also openly reconsidering whether to flip it at all. The car drives well enough that he mentioned wanting to swap in a full black interior and just keep it, which is about as high a compliment as a self-described car flipper can offer a $2,100 Facebook Marketplace find.
What Anyone Can Learn From This Buy
Tim’s E46 flip is a clean example of a principle that applies well beyond the used car market: other people’s discomfort is often just a gap in knowledge. The car had three problems that read as terrifying in a listing and fairly manageable to someone who had done their homework. A knocking engine sounds like an expensive disaster. A water-filled trunk sounds like hidden rot. Mold and grime look like neglect that runs deep.
None of those things turned out to be the end of the story. The knock was a water pump. The water was a clogged drain. The mold and grime washed off. Tim walked in knowing what he was looking at, made an offer that reflected the repair costs, and came out with a clean convertible worth more than twice what he paid.
The broader lesson is that platforms like Facebook Marketplace are full of cars priced by people who want them gone, not by people who have assessed their actual condition. A buyer with specific knowledge about a specific platform, in this case the E46, can spot the difference between a car that looks bad and a car that is bad. Most buyers cannot make that distinction, and that gap is where deals live.
It also helps to have a little nerve. Walking away from 1,000 mocking comments and going back to the garage is not a small thing. Tim did that and came out the other side with a car that made those same commenters do a very public 180. That part, honestly, might be worth more than the $2,100.
