Lot B7565: 2005 Bentley Arnage T Mulliner

Owning a 2005 Bentley Arnage T Mulliner is a wonderful experience, but you’ll want to budget smartly for maintenance. Here’s what to expect:

Annual Maintenance Budget: $7,000-$10,000

This is the figure most Arnage specialists recommend setting aside each year. While basic scheduled services might only run $2,500-$3,000 annually, the hand-built 6.75L twin-turbo V8 in your Arnage T can surprise you with costly repairs if you’re not prepared.

Key Cost Breakdown:

• Oil changes: $500-$700 (not your average oil change!)
• Tires: $1,600-$2,500 every 3-4 years (the Arnage is heavy and needs specific high-performance rubber)
• Insurance: $1,800-$3,500/year (agreed-upon value policy recommended)
• Fuel: ~$2,500/year if you drive 5,000 miles (you’re looking at 10-14 MPG)
• Pre-purchase inspection: $750-$1,500 (essential - fly a specialist in if needed)

The “Get-It-Right” Fund: $5,000-$10,000

If you buy this particular Arnage, I’d strongly recommend having this amount ready immediately. With just 29,416 miles and being 21 years old, this car likely needs all fluids changed (including the special RR363 hydraulic mineral oil), filters, and any deferred maintenance addressed. Low mileage can actually be tougher on these cars than consistent use.

About Those Head Gaskets…

Your Arnage T’s 6.75L twin-turbo V8 shares its architecture with Rolls-Royce engines where head gasket issues are well-documented. The composite gaskets originally used weren’t always up to the task of handling turbo pressure, especially when the engine was cold. This is why many buyers specifically ask whether the head gaskets have been replaced - it’s a $8,000-$15,000+ repair if it becomes an issue.

My Recommendation:

Budget $10,000/year for peace of mind. If you only spend $3,000, great - you’ve got a cushion building. If you need that major service or head gasket work, you’re covered without stress. The Arnage T is a spectacular car - 500 horsepower and 738 lb-ft of torque in absolute luxury - but proactive maintenance is exponentially cheaper than reactive repairs on hand-built British machinery.

Can I help you find a specialist for that pre-purchase inspection, or do you have other questions about the Arnage ownership experience?
