There is not really all that much that I can add to this road test. It is well written and covers most aspects of this 4 speed with overdrive model - exactly the same as my car that I purchased in 1971. I was a little surprised that the engine should have revealed some roughness around the 3500 rpm range, which was not something that I ever experienced.

The main difference between this car and mine, under every day driving conditions relates to fuel consumption. On a memorable all night trip to the North Coast, I averaged sixty miles an hour (in the rain !), with a fuel consumption of 25 miles to the gallon. A totally effortless and safe trip despite the wet road surface, and the car would easily "loaf" along at 80 mph. - and all this with an engine that was well worn !

One modification I have carried out relates to the differential. The diff ratios were as follows:

Mark II A, II B and II C with Auto Box ran a three point nine ratio.
The Mark IIi with Borg Warner thirty five box was fitted with a three point five differential and, quite honestly, it was a somewhat unsatisfactory performer, being quite slow and unresponsive.

The manual four speed with overdrive had a standard four point three differential ratio, but engagement of the overdrive feature on the open road would result in a ratio reduction down to three point five to one. At least two of my cars have been fitted with the Mark III three point five differential which should give a substantial ratio reduction to about two point seven. The cars may well be badly overgeared on account of those differential modifications. One of the reasons why I bought the car that Bryce had bought at the Canberra auction was to provide me with a spare three point nine to one diff ratio. Regards. Styria

I would have thought that 2.7 would be quite a low ratio for the power of the motor. Might not be much fun as you would probably need to disengage overdrive for the smallest of hills. You could probably get away with something like 3.3, but 2.7 seems very low.

I'll be interested in hearing how it goes.

I read that the MKII motors are different manual to auto, with different (lower) compression ratio and I believe different cam. I wonder if this will factor in at all. Power is lower in the auto cars and torque peak is at higher RPM.

Also, with modern tyre sizes the car is going to be under geared compared to when new already.

I suspect that that the tappers are badly in need of adjustment. A "good" Rover engine will be whisper quiet. This one isn't.

Just nit-picking, but the yellow handled screw driver is not a Robver item - had he not described the kit as all original, I would have ignored that shortcoming. Also, a lot of 'stuff' in the boot of the car - a lot of useful or useless spares ? Once knew an owner who made great play of saving old, worn out parts as a means of establishing originality. Getting back to the car again - it is a Mark III, not my favourite version, but nevertheless a beautifully presented car. I wonder about price ? Regards. Styria

As we know Queen Elizabeth II was a fan of the Rover P5 and had 3-4 of them as her personal self drive cars. She is still often sighted driving land rovers on her estates although for security I don't think she drives herself on the roads anymore. Price Charles first car was a P6 2000TC.

Her first P5B, that replaced a P5.


Her Second P5B that replaced the one above

From the british motor museum:

One of the prime ministerial P5B's



And a 1965 P5 Coupe with a manual transmission. Similar to Styria's cars

Seen at CARnivale:





This is a lovely P5B Coupe and I've seen it a few times now at various shows.

Even the rear view amply illustrates the imposing beauty of the Rover. Naturally not to the same extent as some American cars from Cadillac, Chevrolet, Buick, Oldsmobile and others from the '40's, 50's and '60's era, but still quite a bit better than your average sled. With this particular car, the rear headrests are an absolute rarity. The colour scheme - very, very similar to one of my Coupes except for the lack of the Webasto Sunroof that's a feature on my car. Regards Styria

The Rover P5B Coupe on Television and in the Movies. Sections of the video somewhat "Risqué", but it certainly illustrates the "friction locking" adjustment of the front headrest by merely pushing the adjustment lever fully down to lock the backrest. I think it was first seen on the 1963 Rover 2000. Regards Styria

Red face Re: The Rover P5/P5B

Those Rovers are a Class Act. Much to my regret, when I was over hauling their Auto Transmissions I was totally focused on the Job at hand and did not take too much notice of the Car its self. But great to see so many fine examples. Same with all the other vehicles passing through my Workshop, not just Rovers

Well Sean you may, in the not too distant future, once again have some form of involvement with one of the DG Auto gearboxes, that is now in a 1965 Mark IIC. Its owner has spent God knows how much money on that box, and it would seem that still all is not well with the box. I believe, sustained speeds on the open road result in the box slipping - the tacho needle showing 5300 rpm, but the speedo only reaches about 100 kilometres.

Look, it's hard to tell what is what - the owner may be stuck with a mechanic that may just be guessing about this, that and the other, without really being able to pin point the exact nature of the problem - if any. I'll try and help him as much as possible, but there is a limit as to the extent of help I can offer. From what I recall, I did have a Mark IA as well as a Mark II Saloons with that DG box, and they were absolutely splendid performers. I also recall having a box rebuilt by a young technician that ran his own shop at Dee Why, and he had to re-do a box with problems caused by an incorrect valve body gasket. You know, there were holes where they were not supposed to be etc. and just such a little oversight could cause a box to malfunction. Regards Styria
