Fine. Here we go:
a) You are claiming to have a very, very large car budget. £150k is such a huge amount to spend on a car, that 95% of the people in this forum cannot even comprehend what they would do in the same situation. It's just beyond them. Some wont even earn it, in total, before tax, in a decade. Let alone spend it on a car. Therefore, the advice these people will be able to offer is virtually worthless - they can suggest pretty supercars. Great, but you can get this info by flicking through Top Gear Magazine.
b) You appear to be completely oblivious to the fact that £150k is a rather daft car budget. It buys all sorts of ridiculous exotica which as well as being real handful to drive is also a real pain to own. These cars are owned by people who also own other cars, and buy these cars because they love them not because somebody on the internet suggested it.
c) You must know how bizarre your thread looks in this forum, sat right above a thread with people going crazy because fuel is a whole 4p cheaper?
d) Why would somebody who doesn't seem to have an awful lot of car knowledge but aside such a huge budget for the purchase of a car?
e) The other 5% of this forum can comprehend the amount of money you have to spend, and, frankly, the fact you wish to spend it on a car frightens them to death. This, coupled with the fact that before you got this money you were 20 grand in debt at the age of 22 and had a GTI on finance as well rather suggests that finances are something it could be suggested that you suck at. Therefore whatever money you have come into appears to be pretty squandered away on useless crap you neither understand nor need PDQ, and you'll be left with nothing but a destroyed opportunity
f) It's almost certainly a load of bull anyway and we've had loads of people try it on over the years.
I have ONE peice of serious advice for you. If you genuinelly are a normal 22 year old guy who has suddenly come into a vast quantity of cash, go and buy a Golf R32. Currently, its your dream car. You like them. Buy it, brand new, in your favourite colour. Not only does this leave you with hundreds of thousands of spare cash you would be an IDIOT if you didnt invest somewhere, it also keeps you grounded on planet earth. Once you've made the move to seriously expensive stuff its very hard to come back.
