What is the best day of the year to buy a new car?

There is really no "best" day to buy a car, but there is a best time of the year to buy, and it is usually towards the end of a calendar year when most car dealers want to get rid of their inventory to make room for the new year models. Usually the best time to buy starts at September and goes through the end of the year where dealers will offer big rebates and other kinds of offers.

February 29th So long as it lands on a Friday?

the next to the last day of any month ... so the dealer does not have to pay the floor plan fees for that month ..... just do not tell them you know that == AND == remember that those people at the dealerships are not your friends [[ all they want is your money and they will sweet talk you into buying the car that you do not want == beware ,,,,

The best time to buy is when you can afford it but obviously arent pressed for it. I usually hit the year end clearance sales you can pick up really good deals because they want to make room for the year coming up models. But again refer back to the first statement.

That day does not exist

A day not near a holiday. They are moving many vehicles then, on sale, but it's still better from an accounting standpoint. The best advice here is wait until they must sell them or pay taxes on them. There is "inventory tax." This too varies but by the end of March most all really want to sell the cars they would have to pay taxes on left sitting on their lot or in their showroom.

Corporations run on the 'fiscal calendar." I've done minimum research here and I'll be damned if I understand it as it varies on different levels. But I know this much;

June 1 is the beginning of the fiscal year I am alluding to. So I would hazard a guess that the last week in March would be the best time as the dealers would have the most incentive to 'get rid of' the car even though it is a model year older.

What can they offer with the new ride anyway? A fold out pop corn popper above the glove box?

Just a hunch.

Friday 13th.

February 29th So long as it lands on a Friday

The day your bank balance is $1,000 more than what the car costs. That should cover the insurance and registration. (Unless you live in CA. Then you need much more.)

the day you have the money any day that suits you what sort of idiot are you?
