Hello Pompey and congratulations on your choice of user name; I assume you're a fellow PFC supporter sufferer? Me too although I'm based near Fareham.
I've ordered through DTD as well, got a build date for mid-April so expecting car in May - is there anything I should know about the DTD process (mine's coming via JCB in Gillingham)?
Interesting that you asked them not to prep the car - do they literally do no bodywork prep, or do they just remove the plastic wrapping?
Enjoy the car 
Bubba.
Hi Bubba,
Yes fellow PFC sufferer!
My DTD was also through JCB in Gillingham and I cannot praise James enough for his help and like Booth said it is a no frills pick up, my car was outside just ready to go, James had all the papers ready to sign, showed me the controls which was when he noticed the MIB 2 cut out but was fine all the way home. He tried to get my local dealers to change the unit but they wanted the car in and at the time the problem was only intermittent so I could see me taking it in to them and the problem not happening and having to go back countless times! When the unit totally failed I spoke to James and he got the unit ordered in and booked me in to have it changed yesterday.
I signed up to the VW tracking and it all worked like clockwork, most impressed although I know some have had issues.
Booth has done a great write up on new car preparation and I just had them remove the transport covers and the stickers, it still had writing on the window screen! I didn't even have them pressure wash it at all, it rained all the way home for me so it would have been just as dirty!
I used the following:
Autobrite snow foam through their own lance attached to my pressure washer.
2 bucket method to wash with Autofinesse lambs wool mit and 1 separate bucket and Wo-Wo wheel mit to do the wheels
Autofinesse Iron Out
Autofinesse Oblitarate to get the sticker residue off, this stuff is quite strong so just dab it on and wipe off with a microfibre cloth
Autofinesse drying towel and Wo-Wo wheel drying towel
Autofinesse Tripple to give it a very light polish - this also gets the writing off the screen
G-Techniq C2V3 for some winter protection, love this product for the ease of use and the finish and protection it gives. I have a tub of Autofinesse Illusion for the summer to try!
Autofinesse Mint rims
G-Techniq C4 & C5 on the front glass, not brave enough to use G1 yet!
Autofinesse Revive on the plastics
Autoglym fast glass on the inside, I used a glass cloth from Aldi for this and was really impressed for 99p!
I think that is it, I find the snowfoam good but a bit messy especially when it is windy! Just make sure you rinse between each of the decontamination stages.
Worse part is the Santiago wheels to clean and protect, they have a inner groove so might need to invest in some wheel woolies and applying/removing the mint rims probably took as long as the rest of the car!
Now is the time to look at buying your cleaning products as there will be plenty on deals for Easter, Autofinesse have had 20% off and free waxes in the past, Slims detailing is also worth a look for deals.
Booths write up was much more comprehensive than mine so well worth a read!
In all the excitement of picking the car up and wanting to get it home I forgot to take any pictures and only have one of when I finished so will post that when I get chance.
