Do whatever suits yourself, i had the sup TT and loved it and i still do, i wouldn't hesitate at having another (especially a big single:eyebrows: )
though with changing circumstances prevailing, i wanted something with more space, though i didn't want to lose the toys!!!
I've gotta 4.6hse, (see pic) its fully loaded, electric memory cream leather heated seats, fully adjustable air suspension, dipping mirrors when reverse is selected (things like that) harmon kardon sound. loads of things on it to go wrong you may say! but its such a pleasure to drive, totally different to the sup.
I now "cruise everywhere" as opposed to getting on the A1 and try and waste any other high performance car on the road. I do miss the power of the sup, but the 4.6 v8 lump in sport mode isn't that sluggish!!!
The fuel consumpsion IS 14-20mpg, i got mine gas converted within 2 weeks of buying it, i now get about 240-270 miles to a £32 tank full of gas:more:
As i said at the beginning, its you and your missus choice at the end of the day, do whatever suits you's.
If you have any further questions, plaease don't hesitate to ask.
Mike.
