Buy whatever u want. My m3 costs me an arm n a leg in finance costs, insurance, fuel (19,000 miles a year flat out to and from work). It means I can't buy other things however thats the way it is in life. You pays your money and you makes your choice.
I hate the idea of slaving away at this job that I don't like earning pretty well and not enjoying the drive home in the M3.
Lord knows I could do with selling the thing and clearing some debts, instead I just work harder and try and get the biggest annual bonus possible, clearing debts that way
Good luck and fuck whatever anyone else thinks
Cheers
