Ive been looking at numerous WRX's for weeks and the one I finally like has done 123,000 ,its a 2001 model, im reading online these belts need changed every 100,000km.

The guy says hes had it a year and wasn't able to find out if the previous owner swapped out the Timing Belt , so Im now thinking if I buy this car then chances are the belt has not been swapped.

So I assume it will be costly to get done and the purchase of the car alone will empty my bank account, how much does it usually cost to get that belt replaced?..... HELP
