Dont borrow money or sell houses to buy cars, house-property yes, cars no, its not like you could sell it for no loss, every year older means money lost, how much are you going to pay.
R35 GTRs are nice but unless I had alot of liquid cash to spare to pay for it outright and for insurance and servicing I wouldnt touch it.
Keep buying property, make some good $$$$$$$$$$$, then later on buy one, or something better.
If you donot live beyond your means you could have a live a long and happy life and with some good investments buy what you like later in life.
If you live beyond your means, well, look at what happens to countrys like America that are full of the "I want it now" type people, broke, familys in trouble, divorce, dont say "it wont happen to me" because thats what everyone says just before bankruptcy.
Also the you only live once phylosophy is fine if your going to die soon, but if you plan on living to watch your grandkids grow old, it doesnt hold much weight.
