Death Valley was the most incredible place I have ever been. Totally hardcore, roof down most of the way, have pictures to prove it 
Anyway... E39 M5's. I will keep it quick as I'm only having quick internet sessions
You know how much they cost to run and that really, to get a nice one, you need £10-12k. They are not a car you buy with your head. The massive additional cost coupled with the fact that 75% of the time you might as well be in a regular E39 Sport (ie on the Motorway, around town, etc etc) makes it had to justify.
But if you CAN justify spending £12k on an 8 year old BMW then the E39 M5 is one of the most complete cars ever made. They have always been and always will be my dream car - sadly the age of car for the money you pay mean it's likely to be a dream I won't ever realise.
Why am I not buying one*?
a) It looks exactly like my 530i, takes the same time to drive to work in, yet costs loads more to own and £12k to buy.
b) It's an 'old BMW' now. I'm ok, sort of, with owning an old BMW. Not sure I want to spend £10-12k on one.
c) It lacks many of the more modern things you'd expect of a 5 figure sum car - like iDrive, etc.
What am I buying instead? Probably something like a 335i, 630i or a 530i LCI E60. None of these cars are as good as an E39 M5. Very few cars are, infact. But hey, life gets in the way of cars like the M5 sometimes. Even as the worlds biggest E39 fanboy I can't justify £12k and ££££££ a year on an 8 year old 5 Series that looks the same as mine does
But I have nothing but respect for you if you can justify it.
* I'm well aware that if I ever find a mint condition Estoril Blue E39 M5 with Sand Beige interior, I'll probably end up doing something very stupid.
