If you had half a brain, and most people with the means to buy this sort of car do, and you wanted serious suggestions from this forum, you'd have posted 'Imagine you had 150k - what car would you buy?'
You'd then have got nothing but sensible suggestions from a bunch of people who would have assumed it was purely a dream car thread. You'd then have got all the ideas you wanted.
But no, it had to be a I HAVE LOADS OF CASH thread, when its almost certain you probably dont, or if you do you certainly wont have for long given it appears you have the financial nouse of a squashed fruit.
We cant give you advice on what car to buy. a £150k car is a purely irrational purchase for anyone, therefore it is bought and selected purely for irrational reasons. You dont use a £150k car to go from A to B. You dont buy one just to be 'A car'. None of the cars available for £150k are intended to be used as, or are even designed to be used as, conventional normal cars. This is why your thread is crap, this is why you are getting the **** taken out of you.
£150k cars are things like supercars. You dont buy a Ferrari F430 over a Lambo because the cupholders are better and the dealer backup is slightly nicer. You buy one for totally irrational reasons, the cheif being becuase you just 'want' one. Thats the sort of cars that cost this much money.
You don't even BEGIN to have a clue.
The reason why Spie didn't get any hassle, nor did Housemaster, is because neither said LOLZ GUYS LOOK AT MY HUDGE WAD OF CASH?!?!?! LOL WHAT CAR!!!!. They asked specific questions with definate criteria.
You've done none of this.
If you DO buy a £150k car, which I doubt, I rather suspect you'll crash it within a week anyway.
