That's quite a generous concept. Generous to car dealers, those who provide financing, and accountants who can make hay with the 20% loss a new owner enjoys within 12 months via depreciation.
It's the perfect solution if you're a thoracic surgeon.
It's also generous to the makers of the modules, CVT trannies, TPS sensors, and manufacturers of power luxuries, all of whom will be collecting big time on spare parts sales by the time "new was new" starting ticking 5 years earlier...
It's also generous to those of us who are automotive bottom feeders, because it adds to the supply of well-maintained, excellent-driving cars whose depreciation has been completely deducted from the price.
Conceptually, I owe hundreds of thousands of dollars to people who, many years ago, decided "new was new." They all (and I say, thankfully from my own personal point of view) thought it was an "investment" to cough up $28k, $37.5k (average US car, 2018), $55k (average luxury car) and more.
The massive savings from a $5k discount... that's 7.5% of $37.5K... not bad. You'd lose only 12.5% of your "investment" the first year of ownership... you'd have to kiss goodbye forever a mere $4,687.50 in the first year.
Oh, wait -- that completely meaningless loss is just about half what the OP wants to spend...
Judging by your post I'm sure you never had a new car, at least not in the past 5-7 years and all this "stuff" above comes form some yahoo article written by an "expert".
12% discounts on a new base-mid trim is a normal, nothing special thing these days. How about getting close to 20% off? That's something unusual, but possible. 2019 Camrys with 27-28K MSRP go for low 20's and since you can keep this car for the next 10 years the first 2-3 year depreciation will be leveled over the term of ownership.
Financing charges? If you have a decent credit any rate under 4-5% means you are not losing anything on finance, cuz of 4-5% annual inflation rate, I'm talking about actual, real inflation rate. Even first time buyers can get 3% rate, that's a free loan and if you can find 4-5K for down payment and can afford $300-400 payments, that's the smart way to buy a car these days.
And in many cases ppl can find a few extra 100's a month just by changing their life style a bit. I know a younger person that stopped going to bars and restaurants every Friday and found $400 a month to make his car payments without dipping into something else. I had 6 used and 3 new cars and yes, new is new and it's worth it if you bought it right and not killing yourself to make payments.
Sure if you can't afford payments or your credit is shot and you can't get a loan or decent APR you can get a 15 years car for $3K and believe you are smarter than all those dumb new car buyers, but most of the ppl prefer newer design, newer tech, nicer "nobody farted here before me" interiors, warranty and no problems related to old metal and high mileage.
