I'll have to ask you to go in detail about the november easte period. I might be missing something I don't know.Amen: I was about to post the same. It’s always cheaper to delay purchase but the real problem is just finding a good car, if you’re fussy.
Do your research, work out the real options and then pounce when you see the right thing.
But know that no-one in their right mind buys a n old car between November and Easter: use that to your advantage in buying and be aware that it’s a disadvantage when selling
