3 examples.
A MacBook:
12 months on 0% finance through Apple, get it now.
Save for 12 months, get it then.
12 months on 25% finance via a credit card, get it now.
2/3 options get it you now. 2/3 options cost you the same amount. 2/3 options make sound financial sense.
Guess which one of the options is the reason finance gets a bad name?
I don't disagree that spending money on mods is basically pissing it against a wall, but we've all done it. If I could get back every pound I've wasted on cars, I'd waste it on a car.
Oh, and for what it's worth, I've never borrowed to mod. I don't think I would either, but I'm not going to lambast people, they just need to do it right.
