Why's it a wind up, well why do you think?
You came on attacking Sadie for something she'd not said and then made silly comments about Nissans etc. Then after the threads removed you post a question about a car that only a small minority could afford and most would never dream of using one as a tow car!
So who did you think was going to give you advice?
If you can afford a Six Litre car that is of a style suitable to tow a caravan do you expect it to be lacking power?
Or maybe that its not heavy enough?
May be it gives a poor ride?
Leather seats to squeaky?
Could it be that you think somebody could advise on fuel consumption and that it will be a miracle car and return 25mpg when towing?
Or are we to believe that you would be concerned about fuel consumption costs and that you need advice on remapping to economise as you can't really afford the fuel although you can afford a 100k plus car.
Personally when spending money on cars I prefer a car suited to towing and seperate performance car.
As you advised us that you are around 70 years old your reactions are likely to be a little slow for such a high powered car no matter how fit you may think you are!
If you really want a Six litre VW buy the big Q7 diesel, there are good deals available and you'll have a good tow car far better suited to caravanning and change left over to buy a fast sporty job
The V12 7 is not quite as quick as my Q7, but then I have age on my side.
