Well since I would never base my choice on car on kids or needing big space, I'd most certainly pick the Audi TT-RS.
In Sprintblue color, ordinary sportseats (not the silly bucketseats) in Alcantara black/black/silver and otherwise fitted with all the goodies.
Maybe without the spoiler at the back.
Realistically I'm looking at a TTS right now, but would of course want the excellent engine in the TT-RS. Unfortunately, the pricedifference here is the equivalent of 50.000 pounds...
That said, I think the TG Hilux wins this thread.
MTM RS6 R. Because the practicality of a station wagon combined with the awesome of a 730 hp V10 is all I'll ever need.
Oh, wow, I think that might be the truck from Tremors 2: Aftershocks. I just watched that movie last week. I hadn't seen it in ages.
I don't know trucks very well... but he said something about it being a 'mil-spec deuce-and-a-half'. Some googling revealed that mil-spec means military specification and knowledge that I already had suggests that deuce and-a-half means two and a half.
So is that what that is?
I can see a hood bulge, but it doesn't look all that bad to me. I've seen a couple of RS4s in the flesh, and I think it looks subtle at a glance, but menacing in the details. A quick glance and you could mistake it with an A4 or S4, but have a better look at the small details and you'll begin to see that what it really is, is an RS4.
If you are going for "end of the world" vehicles then it's hard to beat this:
Tough as hell, hauls all your survival gear, provides shelter, and it will run on just about anything you can put in the tank - from diesel to kerosene.
