When I planned to buy a car in 2021, I specifically researched the zero-whole ratio, which is the ratio of the sum of the prices of all car parts divided by the price of the whole car. At that time, the zero-whole ratio of the C-Class was as high as 650%, meaning even a small scratch repair could cost several thousand yuan. I almost chose it, but a friend reminded me that the Toyota Camry's zero-whole ratio was only 280%, saving more than half on repair costs after an accident. I ended up buying the latter, saving a lot of money. This affects insurance and maintenance expenses—if the zero-whole ratio is high, like with luxury cars, ownership costs skyrocket. During the pandemic, parts were also in short supply, making prices even more unpredictable. Before buying a car, check the China Insurance Association report—don’t just look at the car price, or you might regret digging deep into your pockets later.

I've been working in auto repair for many years. In 2021, I witnessed a sharp surge in spare parts prices. The 5 Series had a parts-to-whole ratio of 550%, and replacing a headlight assembly could cost over 10,000 yuan, leaving car owners overwhelmed. In comparison, the Honda Accord had a parts-to-whole ratio of around 350%, with more affordable and durable components. The parts-to-whole ratio is closely tied to brand strategy—luxury car parts are priced aggressively but offer stable quality, while mainstream cars like the Ford Focus, with a ratio just over 300%, provide quicker and more worry-free repairs. I advise customers to regularly check their vehicle's condition and address minor issues early to save big on repairs. Since that year, cars with lower parts-to-whole ratios, such as Kia, have sold well, leading to fewer after-sales complaints.

Having worked in the business for over a decade, the parts-to-labor ratio directly determines premiums. In 2021, the Audi A4 had a parts-to-labor ratio of 620%, leading to higher claim payouts and owners paying 15% more in annual premiums. Ordinary brands like the Volkswagen Passat had a parts-to-labor ratio of 330%, making their insurance policies cheaper and more affordable. Data fluctuates significantly, with supply chain issues driving up the cost of imported parts. Overlooking this factor when choosing a car means paying more year after year.

I'm obsessed with car data, and the 2021 Zero Whole Ratio Report is eye-opening. The ES has a ratio of 350%, with excellent maintenance affordability; the Porsche 911 exceeds 1000%, where replacing a set of parts could bankrupt you. Brand differences are significant, with Infiniti at 400% being mid-range. This affects used car residual values—cars with high zero whole ratios depreciate faster. During the pandemic year, parts shortages led to severe price hikes, so considering this when buying a car can save future expenses.

From an economic perspective, the zero-whole ratio increased by 10% in 2021 due to supply chain disruptions and parts scarcity. maintained a high-price strategy at 600%, while Toyota excelled in controlling the ratio within the 250%-300% range. Consumers are shifting towards low-cost models, putting pressure on after-sales services for vehicles with high zero-whole ratios. Government data calls for manufacturers to reduce prices to alleviate the burden on people's livelihoods.
