what's the most amount of money you've spentWatch this thread
Otherwise, it's my current car and a blow-out trip to the USA/Canada, both of which cost more than you are planning to spend, OP.
Car years ago.
Australia - five weeks. Often back-packing. Thousands - but worth it.
Irrelevant to this but most expensive cost added up over the years in one way or another - being a parent.
Most on actual thing was about 1500 on a self build computer system.
