The worst part I reckon is having to press a pedal to change gear!! Why do that when a perfectly good autobaox comes with every car??
I have my Auto Cossie. Wife has her 55 plate megane cabrio auto... even my Corsair is an automatic!
Manuals are so 1980's!

A Cossie really needs that extra grunt doesn't it!

Depends on where you do your driving. For stop-start and town use you can't beat an auto, but for long distance motorway cruising where you don't change gear much there's no reason not to have a manual. Does make me wonder why all the large motorway cruisers are autos and the little town cars manual though...
Personally I prefer autos because they're smoother than manuals, especially when pulling off, but they do sap engine power and therefore fuel - which is something of a concern when the engine is already a thirsy beast. The reason they use more fuel is because they generally have less gear ratios than the equivalent manual (so the gearing is a compromise to start with), the engine needs to drive a hydraulic pump to operate the gearbox (which adds to the weight as well), and there is the loss/slip in the torque converter under certain conditions as the lock-up clutch isn't permanently engaged. These are the reasons that autos are nearly always less efficient and slower than the manual versions.

What a load of technical tosh.... the only reason to have an auto is so you can drive round town and still eat a Big Mac, chips and coke without worrying about changing gear... as for economy - get LPG. Apparently mine has it, but I don't like to mention it!!

But incorrect technical tosh at that !!
Modern auto boxes are far more efficient then older ones.
With a bit of electronic tweaking you can get 5 gears and lock up out of a 4R44E (electronic Scorpio auto box).
This then effectively gives you 6 speeds, a sight more efficient than a 5 speed stick waggling clunker. Trouble is to get the correct effect you'd also need to change the diff for a 2.3 or 2.0 unit......blah blah blah

The easiest way to make the whole car more lively and still retain a real 145 MPH is to change the diff, as these cars are overgeared from the factory.
Highlander put a 2.0 litre diff in his, along with the 2.0 litre speedo drive gear and he said its like a missile.

People have fitted manuals.
Guess it's what you prefer or use too.
But the clever guy would keep the auto & look into modding it.
Modern auto's can be made into very clever manuals err infact the very latest manuals are a sort of auto/manual hybrid
Yes they are over geared, the diff thing really works.

Hi Dave,
Dont know if you saw my other post re diffs ?
Dont really want to go all out on my Cossie Estate by fitting a 2.0 diff, but do you think the 2.3 diff would be a worthwhile option bearing in mind I do motorway driving a lot with mine as well as the local stuff ?
I dont know of anyone else who may have tried a 2.3 diff.

Hi mate.
Well a 2.3 will be better but not as good as a 2.0L for performance.
As you know it's a balancing act between mpg & performance so you may win a little on MPG.
The gearbox is the same so if you work out your peak torques at the wheels with different diff ratio's you will see what kind of effect you will have.
Remember a 2.3 diff is a 3.9 not as stated on the main site.

Thanks for the reply Dave.
I kinda figured that, so I reckon I'll give the 2.3 diff a go, cos the car is ok, just a bit slow off the mark.
All said and done it is a big estate car, so I dont expect exocet performance, but a bit quicker away from the lights, and still retaining a modicum of fuel economy would suit this car.
Another job on the to do list !!!!
Still waiting for a completion date from the Scottish solicitors LOL, they seem to only work 1 day a week
Still hopefully we'll be moved in for the end of the summer
Regards Dave

Roy,
If you can get your gearbox to me I'll rebuild it and guarantee it for parts plus a drink, say £450.
2 - 3 day turnaround.
I'm semi retired these days but still do a few and still have all my equipment etc in my workshop at home.
Hope this may help you,
Regards Dave
