Are you sure? My understanding is that the moon reflects very low levels of UVa and UVb, at levels so low you cannot get "moon burn" and therefore would not have any significant effect on paint fade...
The sound difference may be down to the different exhaust systems?
If you want loud:
replace the oem exhaust system + remove the cat
remove the rear seats and parcel shelf
remove the acoustic valve
I think they look stunning from that angle but look a bit of a dogs dinner from the rear. Don't quite understand why they are so expensive. Would be interested to hear how they compare against the T. Presume it has runflats?
I wish forum members could not post "any" comments on "for sale adverts" as it more often than not becomes a pi$$ing contest. If you're interested in a car then get in touch with the owner and discuss it directly.
As an aside, the new 911 GT3RS 4.0 uses many CF body parts. All panels are painted. Seems extra material, such as resin, has to be used to make exposed CF look good. This adds to the weight. An anorakish fact I like.
I wouldn't recommend Tesco fuel these days, rumour has it they are buying and shipping direct from Holland, and are cost cutting on the additives. I know a few local people who have had engine problems over the last 6 weeks. You have been warned.
