To take the other side of the coin: The Rolls will not be a dd. It only has to make it back and forth to a couple of weddings a weekend with only the appearance of reliability. Since a Rolls is a maintenance nightmare, there are fewer of them available for new brides so you make be able to find a nice niche in the market.

or.... or...

buy a prius and stretch it... That will cater to the "green" wedding people

Not really. All cars are made to be used. Using a vehicle only occasionally makes a car deteriorate at a worse rate than one driven constantly. - taxis last far longer in mileage rate than the average daily drive.

When you do a wedding the car is used for very little miles at a very slow speed.

Whunter could you post the link again. It links back to this thread.
Thanks for all the replies, the idea is just that. I saw a cheap RR that is 20 minutes away from me in california, he pic looks like a clean car with hydraulic pneumatic problems. No smog required. I was actually looking for pre smog MB's I thought that a car as classy looking could make a good Bridal car. That's all.

After you replace the fluid, wait about a week and drain it all one more time.

Would this be a good way to flush the hydraulic system on SLS Benzes, 6.9s, etc.? Gets pretty expensive to change with official Benz hydraulic fluid repeatedly just to clean things out...

X3

I know it's being done for a potential business but it did sound like a contradiction to me.

I wonder how many people would be interested in hiring a 600 for a wedding

Well, yeah. I didn't tell him the car has to be in N or P, either. My bad.

Alex,
I'm still trying to find out the composition of the hydraulic fluid, in order to answer that question. If the composition is a vegetable oil-based fluid, then this would work. I doubt that. I think it is more likely a mineral-based fluid, but even whunter doesn't know that, and is checking for me.

If someone can take a photo of the container that holds the hydraulic fluid, especially the German version which has to give more info, by law, that might help.

In that case (of mineral oil-based fluid), there would be little or no need to do a flush, unless the system had been really neglected. LHM, the mineral oil-based hydraulic fluids, can be flushed with stuff like Dexron, or a whole set of commercially prepared flushes that keep the particles in suspension so all the resdue comes out with the fluid. Then change the filter in the system (assuming it has one, Citroens do) and voila! you be flushed. Add new fluid to the correct level and have fun with your suspension!

Have a great day.

After reading the complete post and looking at sites, I have decided that the ownership of a RR is not for me. I'll go back to the garage and work on my great SL.

Thanks. W Hunter.

ROLLS ROYCE BRAKE FLUID 1LTR

CASTROL RR363

ONLY FOR USE IN THE HYDRAULIC SYSTEM OF ROLLS ROYCE AND BENTLEY CARS REQUIRING CONVENTIONAL BRAKE FLUID.
MUST NOT BE USED IN SYSTEMS REQUIRING MINERAL OIL.

MUST NOT BE USED IN ROLLS ROYCE CARS FITTED WITH GREEN CAPED HYDRAULIC SYSTEM RESERVOIRS

Silver Shadow Braking System.
Have you ever wondered why the Silver Shadow more than any other Rolls-Royce Model had issues with their central hydraulic systems if maintenance was neglected.

#1. A typical issue occurs because theses cars are abused, usually setting for months or years ignored, not run or driven = This is abuse.

RR 363 Hydraulic Fluid is damaging the inside of the rubber hoses.
The factory workshop manual states with extreme/dire safety warnings that the rubber hoses MUST be replaced every six years, because the fluid degrades the hoses from inside like a slow corrosive.

FYI:
Most of the time when the brake calipers are locked; and quite often at the rear, it is due primarily to the collapsing of the rubber inside of the brake hose that connects between body and caliper.

The collapsing of the inside of the rubber hose will allow the fluid to go to the caliper because of the tremendous (2000 PSI) central hydraulic system pressure; but: there is a BUT.

The same fluid that was allow to go to the caliper can not return to the central hydraulic system reservoir, because the collapsed rubber hose acts as a one-way valve; causing restriction and pollution such as dark brake fluid.

When you see dark fluid into the sight glass of your central hydraulic system reservoir, it is a warning that some or all of your rubber hoses are starting to disintegrate internally.

Replacing the hoses and flushing the entire system is a critical safety issue at this point = Do it or death can result.

#2. Failure to flush the central hydraulic system every two years.

This allows the RR363 to break down into the typical GREEN sludge seen in the central hydraulic system reservoir sight glass.

If you are LUCKY, flushing the sludge will flush out.

If you are not lucky, the damage can (February 21 - 2010) cost $22,000.00 USD to restore the central hydraulic system = giving the car brakes again.

The composition of RR363 is a (trade secret, copyright, patented) vegetable oil-based hybrid fluid.

The factory workshop manual goes to extreme measures, making it clear that the only authorized hydraulic system cleaner allowed is denatured alcohol.

NOTE:
When fully rebuilding components off the vehicle, I will use CRC brake cleaner, CRC electrical cleaner msds,

You are welcome..

IMO:

* If a person is not wealthy enough for the RR dealer to do all service, or LOVE Rolls-Royce and/or Bentley enough to DIY all repairs, don't buy one.

I used plain old DOT 3 brake fluid with excellent success. It wasn't unusual to go through a coupla quarts of fluid in the process of brake/suspension work.
Other than the flex hoses going to the calipers, I either made up my own hoses and hard lines, or bought surplus aircraft hoses from a nearby outlet.
