Recently, Road & Track spoke to several high-end mechanics familiar with the insane world of supercar maintenance. We're talking four-figure oil changes and engine rebuilds within spitting distance of the cost of a brand new 2015 BMW M235i. The owner of McLaren F1 chassis No. 072 is about to experience the extreme economics of this kind of maintenance firsthand. There's a silver lining, however: it's virtually impossible to total a car like this.

Why? The man who maintains Ralph Lauren's beyond drool-worthy collection of ultra-rare exotics, Mark Reinwald, puts it into perspective: "The car is appreciating so fast the repair bills will never catch up to the price."

Here are six incredible facts we learned about McLaren F1 maintenance.

1. There's nothing routine about an oil change

A routine oil change service costs about $8,000, and annual running costs are estimated by McLaren to be about $30,000 per year. It's not something one Jiffy Luber can do—more like a Hugo Boss-attired pit crew. [Inside joke—Ron Dennis requires all McLaren workers to wear supplied uniforms made by Boss, including underwear.]

2. Prices aren't going south anytime soon

The last one of about 100 built from 1992 to 1994 sold for $11 million.

3. Don't run over a nail

Bryan Murphy, a technician who cared for three customer F1s, reports that a nail in one tire cost $6,000 to repair because the McLaren factory insisted on replacing both tires on the same axle. The McLaren factory scrubs every F1 replacement tire that it supplies to owners on a test track.

4. It will be in the shop every year, no matter what

Ralph Lauren sends his three McLaren F1s to the main Woking, Surrey, U.K., McLaren headquarters for their service, which is officially required once a year. Factory shops are also located in Germany, Japan, and Australia as well as two in the U.S.

5. When it's in the shop, it's away for a while

McLaren says service can take one to six weeks, with the quickest "door-to-door" being air-freight at 10 days, or seven weeks if shipped via sea. McLaren has two full-time F1 techs in the UK headquarters.

6. The engine will have to come out at least every 5 years

Routine service is required annually; the rubber fuel cell service every five years requires the powertrain to be removed. Wheel bearings, hubs and locating pegs need to be replaced regularly.
