The Cosmo is similar in concept to the Soarer TT, which did have a manual option.

Very few manual Soarers were sold.
Manual option was only on some engines though, no manual for the V8.

And it's not uncommon elsewhere. Similar concept, albeit maybe pitched slightly differently. But Jaguar XJ-S was mostly automatic, ok you could get a manual 6 cylinder one, but very rare. V12's only ever auto.

BMW 8 Series, did they even offer a manual on the 840/850 models? If so, it was the rare option.

Porsche 928's, yep manuals where available, but I suspect most ended up being auto's. Certainly seems that way when you look at the classifieds.

Plenty of US market luxury coupes that are main auto only too.

I was looking at these a couple of years ago to complete my rotary set (already have an RX7 and rotary mx5). Good ones were coming up at ~£6K. I had hoped they could fit two kids in the back but the rear is too small for such a large car.

Cosmo Manual gearbox conversions have been done and with turbo changes, you can easily get 400-500bhp if that's your thing. A lot of money to put on an old car.

I'm told that better shocks really improve the handling. Reliability is good but the electronics are difficult to get repaired, often needing to go back to Japan to get fixed.

Many of the 20B engines have been removed to go into FD conversion.

Gotta love a 20B. Here's the worlds fattest man running one in an RX3 to run a pretty wild looking 7.1 quarter:

BMW did offer a manual in both the 840 and 850. They're quite rare, especially in the 850, but they exist

Also the XJS was available as a manual V12 for a while:

The manual gearbox V12 version was produced from 1975 until 1981. During this time only 352 manual vehicles were produced, making it a rare machine

I drove one many, many years ago and from memory it was a 4 speed gearbox. I remember it being absolutely awesome, a totally different proposition to the early 3 speed slusher. Jaguar always did seem to lose an awful lot of horses from that V12 between engine and road, even my late XJ12 with the 4 speed GM gearbox never felt like a 320 odd bhp car.

You are correct I'd completely forgotten about the 4 speed manual early V12's. Nothing HE or newer V12 was manual from Jaguar directly. But like the XK8/R.

As for the 3 speed auto, it's a GM400, used on loads of American V8's. The V12 was a bit over geared IMO. The latter 6.0 ones had the 4L80e 4 speed. These went very well, we had an XJ40, very rapid and very smooth.

Nice one, always loved these, or the idea of them at least, never seen one in the metal.
Is it this exact car?
Looking forward to photos and progress updates.

Congrats! Would make a great Readers Cars thread, and I'll be interested to hear how it drives when you get the chance.

I usually find the use of 'FTFY' irritating and unoriginal.

Not this time. thumbup

There is a difference between a rotary aero engine and a radial aero engine.

Look it up. smile

Every day is a school day. Looks like 'rotary' has been used twice for rather different applications, proving (as if BL hadn't already! wink ) that engineers aren't infallible! biggrin
