I've been putting 250 aside for 4 months with no problems at all thats including paying a phone contract. I still end up having 200 for personal use.
If I take out a loan, buy the car.. I feel it's exactly the same as saving only you have the car whilst you save so to say, Get now pay later rather than save! I'd be putting 90 to the car and still have around 350 (60 a month insurance) I'd still be putting less than 250 a month aside, it'd be instead 110.
I'm currently doing 250 to save for the car fast but I feel it'd also save me some stress as I'd have a year to pay it back rather than rush-saving within a 6 month time frame.
Apologies i'm babbling, Thanks so much for helping!
