Turning down the junkyard when it later offers to buy that same supposedly broken Bentley back for $10,000 takes things to another level.That is exactly the situation Rich Benoit of the Rich Rebuilds YouTube channel found himself in with a Bentley Arnage that had reportedly been sitting in a salvage yard for years. The car was believed to have a blown head gasket, a repair that Benoit estimated could easily turn into a $20,000 headache.When the junkyard unexpectedly offered him twice what he had paid to return the car, Benoit began wondering whether the seller knew something he did not. Still, he rejected the easy $5,000 profit and decided to continue diagnosing the Bentley instead.AdvertisementAdvertisementAs documented in a recent Rich Rebuilds video, that gamble may have paid off. After working through the car's problems one by one, Benoit eventually got the massive British luxury sedan running properly, then spent surprisingly little turning it back into something resembling the six-figure status symbol it once was.The Bentley Was Supposed To Have A Dead EngineImage Credit: Rich Rebuilds / YouTube.The biggest concern was the Bentley's 6.75-liter twin-turbocharged V8, particularly after the car filled the shop with smoke during an early startup attempt. A failed head gasket on an Arnage would have made the cheap purchase considerably less attractive.Benoit first pressure-tested the cooling system and found that it held approximately 15 psi without an obvious external leak. He then used a combustion-leak tester, which did not indicate combustion gases entering the cooling system, giving him confidence that the head gasket might not be the disaster everyone feared.An oil inspection also failed to reveal the kind of catastrophic metal contamination that would suggest major internal engine damage. The oil did smell somewhat like gasoline, however, pointing toward a possible over-fueling or misfire problem rather than a mechanically destroyed engine.Old Fuel May Have Been The Real ProblemThe investigation became especially interesting when Benoit inspected the spark plugs. Several showed signs of fuel and oil contamination, so the complete set was replaced before he moved on to checking the intake system for vacuum leaks.AdvertisementAdvertisementA smoke test failed to reveal any obvious cracked hoses or major leaks, leaving the fuel system as one of the remaining suspects. That turned out to be important because the Bentley had reportedly been sitting for roughly six or seven years before Benoit acquired it.Fuel removed from the tank looked noticeably discolored compared with fresh gasoline and appeared to contain water. Benoit drained and filtered the contaminated fuel before returning usable gasoline to the tank, then cleared the car's stored fault codes and prepared for another startup.This time, the result was dramatically different. The Bentley settled into an apparently smooth idle without the previous severe misfire, produced no significant smoke, and showed no immediate check-engine warnings.Turning Down $10,000 Suddenly Looked SmarterImage Credit: Rich Rebuilds / YouTube.Benoit also confirmed that the transmission was functioning, meaning the Arnage could once again run and drive. At that point, the junkyard's $10,000 offer no longer looked nearly as tempting as it had when the car's mechanical condition was still a mystery.AdvertisementAdvertisementThe project had already benefited from a series of extremely budget-conscious repairs, including fixes to the braking and airbag systems using inexpensive or adapted components. Benoit's entire approach was built around seeing just how cheaply a former $300,000 luxury sedan could be rescued.Once he became convinced the Bentley was mechanically worth saving, however, he decided to spend some actual money improving its appearance. The damaged front fender, deteriorated upper paintwork, roof, and mirror caps were repaired by a small body shop for less than $2,000, according to the video.An $8,000 Bentley That Actually Looks ExpensiveA set of 22-inch wheels sourced online followed, along with new tires and tire-pressure sensors. Benoit estimated that he was approximately $8,000 into the entire project after accounting for the original purchase, repairs, paintwork, wheels, and tires.The finished Arnage looks worlds removed from the neglected salvage-yard car that was supposedly headed toward dismantling. It still has a few details to sort out, including front-end ride height and occasional tire rubbing, but the major mechanical nightmare that supposedly justified its bargain price never materialized.AdvertisementAdvertisementPerhaps the junkyard simply realized the Bentley was worth considerably more intact than it had initially assumed. Whatever prompted that $10,000 buyback offer, Benoit's decision to refuse it appears to have worked out rather well.He now has a running, driving Bentley Arnage that cost him a fraction of what even a decent used example would normally represent. For once, saying no to easy money may have been the financially responsible decision — although buying a $5,000 junkyard Bentley is still probably not a strategy most financial advisers would recommend.If you want more stories like this, follow Guessing Headlights on Yahoo so you don't miss what's coming next.
