The 50 mph + is better than many subsequent tests. Because of the risk of a slight imperfection in the surface few are sufficently brave or foolhardy to corner at 50 mph at the limit, but at more usual speeds roll is not minor. On twisting road a colleague used to say riding in my RP reminded him of his yatch. And that was with shock absorbers tight.

I see there is a bit of contradiction, First it states" and up to a point it can be said that the car's behaviour on the new third gear is as much as it was on the old second" whilst towards the end it states " on third gear the car can do 35 mph" I've never managed 35mph on a crash 4 speed box RP or second in an 3 speed RN, the tester must have been flogging it.
The art department has been at it, the door finger plates aren't the full width of the door, whilst the clutch pedal has disappeared or moved to the right of the steering column, whilst the engine has the correct short fan pulley used on the 4 speed engines. I think this refers to the 4 speed RN saloon with the 26VEHG carburettor with the combined manifold which restricts access to the tappets and didn't have the Bakelite cover over the ignition and throttle levers.

My RP saloon, admittedly with the 4 speed 'crash' box, which has a lower third gear ration than the synchromesh box (1.74 to 1 as opposed to 1.66 to 1 for the later box) has been timed (by a friend in their Porsche Boxter) at 51.6 mph 'flat out' On 3.50 X 19 wheels, this equates to 3500 rpm. The same revs in third, gives a theoretical maximum in third of 29.64 mph and a tad over 31 mph with the synchro box. However, taking the car to that speed in third, it gets awfully busy mechanically, and I am usually in top well before 25.
35 mph in third therefore sound a touch optimistic to me, unless the speedo on the test car was a bit 'fast'.

Oh I forgot to mention it has a Magmo speedo which are difficult to read.
