Données de substitution — aucune enquête directe sur les regrets n'existe pour cette décision. Les taux sont dérivés des scores de satisfaction et des obstacles d'accès plutôt que de questions portant directement sur les regrets. Voir les mises en garde ci-dessous.

About 39% of Americans who have bought a car report some form of
purchase regret, according to a LendingTree survey of 1,919 US car
owners. That figure covers all buyers — new and used combined; the
survey never separates the two, so it cannot tell us whether new-car or
used-car buyers regret more. The most common regrets are choosing the
wrong make or model (14%), overspending (10%), and not shopping around
(8%). Among recent buyers the rate spikes to 47%, then decays to 24%
for those who bought six or more years ago. A second all-buyer source,
CarGurus’ 2024 Consumer Insights Survey (n=3,150), found 79% of buyers
satisfied — again not broken out by new versus used, and satisfaction
is not the same thing as regret. Because no source isolates new-only
from used-only regret, both sides of this pair carry the same 39%
all-buyer baseline, and this entry is flagged as a proxy.
The financial mechanism is plausible even without pinning down exact
figures: new vehicles carry a substantially higher purchase price and
monthly payment than used ones, and depreciate fastest in the first
year or two of ownership. Buyers who stretched their budget are
disproportionately represented among the regretful: the LendingTree data
shows Gen Z buyers, with thinner financial cushions, regret at three
times the boomer rate (60% vs 20%). Used-car buyers commit less capital
upfront and face lower monthly payments, but trade certainty for risk —
mechanical surprises and higher maintenance costs are the primary pain
points. Cox Automotive’s 2023 study found 49% of all car buyers paid more
than expected, a figure that cuts across both segments but likely stings
more against a higher new-car baseline price than a lower used-car one.
The honest answer is that the survey data cannot rank new against used.
Neither the LendingTree nor the CarGurus study isolates new-from-used,
and the CarGurus figure measures satisfaction rather than regret. The
financial argument that committing more capital to a faster-depreciating
asset should generate more regret is plausible, but no source in the
evidence base actually measures it — so this pair reports the same
all-buyer regret rate on both sides and no measured gap.

[1]LendingTree — Nearly 4 in 10 Who Bought a Car in the Past Year Have Regrets
Étude primaire
39% of Americans who have bought a car have regrets about their purchase; 47% of those who bought within the past year regret it
Extrait
“"Nearly 4 in 10 (39%) Americans who have bought a car have regrets about their purchase. Among those who purchased a vehicle in the past year, 47% had regrets, but this decreased as ownership terms lengthened, reaching a low of 24% for Americans who bought a car six or more years ago."

LendingTree commissioned a Qualtrics survey of 1,919 US car owners (Dec. 14-20, 2021 per the published methodology). The 39% figure covers ALL car buyers (new and used combined). The survey does NOT separate new-only from used-only regret — no new-vs-used breakdown exists anywhere in the source. We therefore cannot attribute a distinct new-car regret rate; 39% is the all-buyer baseline that applies to both sides of this pair (proxy_only). Among recent buyers (past year), the rate rises to 47%, decaying to 24% for those who bought six or more years ago.
[2]Cox Automotive — Cox Automotive's Car Buyer Journey Study Shows Satisfaction With Car Buying Improved in 2023
Étude primaire
69% of consumers were highly satisfied with the buying process in 2023, up from 61% in 2022; 49% paid more than expected
Extrait
“"The 2023 Car Buyer Journey Study presents a noteworthy increase in overall satisfaction, with 69% of consumers being highly satisfied with the process compared to 61% in the 2022 study. Regarding the price paid, 49% of buyers report paying more than expected, down from 54% in the 2022 study."

Cox Automotive's annual Car Buyer Journey study tracks satisfaction across the full buying process (new and used). The 31% not-highly- satisfied figure is consistent with LendingTree's 39% regret rate given different question framing (satisfaction vs regret). The 49% who paid more than expected provides context for why price-related regret is common.

Same LendingTree all-buyer survey used on the action side. Because the survey never separates new-only from used-only regret, there is no distinct used-car regret rate to report; the used side inherits the same 39% all-buyer baseline (proxy_only). Regret decays with ownership length (47% recent -> 24% at six-plus years), but this is a duration effect, not a new-vs-used effect.

CarGurus 2024 Consumer Insights Survey (n=3,150: 3,008 opt-in + 142 CRM sample). The 79% satisfaction figure covers ALL car buyers (new and used combined), not used-only, and satisfaction is not a regret measure. Its complement (21% dissatisfaction) is offered only as loose corroborating context that overall discontent is well below half; it is NOT used as the used-side regret rate.
Réserves
Les deux côtés utilisent désormais des données basées aux États-Unis, éliminant le facteur de confusion inter-pays antérieur. Cependant, aucune des deux enquêtes n'isole nettement le regret des voitures neuves seules de celui des voitures d'occasion seules. Les 39% de LendingTree concernent l'ensemble des acheteurs de voiture confondus ; nous les attribuons à « acheter neuf » parce que les regrets les plus courants (dépenser trop, mauvais modèle) sont corrélés aux achats de voitures neuves à plus fort enjeu. Les 21% de CarGurus sont un inverse de satisfaction, non une mesure directe de regret — les acheteurs insatisfaits ne ressentent pas tous du regret, et certains acheteurs pleins de regret peuvent tout de même se déclarer satisfaits. L'écart de 18 points suggère que les acheteurs de voitures neuves éprouvent un regret modérément plus élevé, cohérent avec un engagement financier et un choc de dépréciation plus importants, mais le schéma est plus proche de l'équilibre que fortement unilatéral. Les effets générationnels restent importants : le regret de la génération Z (60%) écrase celui des baby-boomers (20%) dans les données LendingTree, suggérant que le stress financier et l'inexpérience sont de meilleurs prédicteurs que le statut neuf-vs-occasion. Les données d'enquête proviennent exclusivement d'échantillons des États-Unis ; les taux de satisfaction et de regret dans les pays aux structures institutionnelles différentes — normes de consommation, tarification et structure de marché — peuvent différer considérablement.
