The used car market is entering spring with serious momentum. The Manheim Used Vehicle Value Index climbed 6.2% year-over-year in March to 215.3 — the highest reading since summer 2023. Wholesale values rose 1.4% in March alone, well above typical seasonal norms, and are up 2.3% since the start of 2026.
Against that macro backdrop, our proprietary AI is generating forecasts across 548 vehicle segments this week. Here is what the data says.
This week's signal split
Across every segment we forecast, the distribution looks like this:
- HOLD signals: 363 segments (66%) — prices forecast to stay within ±1.5% over the next four weeks
- BUY signals: 105 segments (19%) — prices forecast to rise more than 1.5%
- SELL signals: 76 segments (14%) — prices forecast to drop more than 1.5%
More buy signals than sell signals is consistent with the broader market heat. When two-thirds of segments are holding steady and a fifth are rising, we are in a stable-to-bullish environment — good news for sellers, a challenge for buyers looking for deals.
Top 5 price risers (4-week forecast)
These are the segments our AI forecasts will see the largest price increases over the next 30 days, ranked by percentage change:
| Vehicle | Current Price | 4-Week Forecast | Change |
|---|---|---|---|
| 2013 Ford F-150 | $25,000 | $29,897 | +19.6% |
| 2008 Mercedes-Benz SL550 | $8,500 | $10,134 | +19.2% |
| 1988 Porsche 928 | $10,000 | $11,899 | +19.0% |
| 2016 BMW 750i | $15,100 | $17,842 | +18.2% |
| 1966 Cadillac Eldorado | $25,000 | $29,390 | +17.6% |
A couple of things jump out. First, the truck segment continues to command attention — that 2013 Ford F-150 tops our risers list and aligns with the broader truck strength we are seeing across wholesale auctions. Used truck and SUV prices are expected to finish 2026 up 1-5% on average, according to industry forecasts.
Second, mid-era luxury coupes and classic convertibles dominate the top of the list. The 2008 SL550, the 1988 928, and the 1966 Eldorado all reflect a collector market that continues to reward well-preserved examples. The classic car market hit $4.8 billion in 2025 and new-collector demand is keeping momentum into 2026.
Top 5 price fallers
On the other side of the signal, these segments are forecast to soften the most:
| Vehicle | Current Price | 4-Week Forecast | Change |
|---|---|---|---|
| 1978 Ford F-150 | $40,500 | $32,834 | -18.9% |
| 1964 Ford Galaxie | $37,000 | $30,312 | -18.1% |
| 2016 Mercedes-Benz Sprinter | $47,610 | $39,162 | -17.7% |
| 2001 Chevrolet Corvette | $26,269 | $21,632 | -17.6% |
| 2017 Chevrolet Corvette | $60,750 | $50,578 | -16.7% |
Note the split: while the modern 2013 F-150 is rising, the 1978 F-150 classic is forecast to drop. This is the collector vs. utility divide playing out — older trucks that had run up hard during the pandemic-era collector boom are giving back some gains, while the late-model daily-driver truck segment stays hot.
Corvettes are a standout here. Both the 2001 C5 convertible and the 2017 C7 convertible show material downside in the 4-week window. Sports cars in the $25K-$75K range have shown thinning bidder depth at recent auctions, consistent with the broader observation that generational turnover is reshaping demand.
What to watch
A few themes to pay attention to this week:
Macro context matters. The Used Car CPI reading is 179.83 as of March 2026 (our database tracks this from the BLS via FRED). That is down from January's 181.27 — a small macro softening even while wholesale prices climb. The gap between wholesale strength and retail cooling is worth watching.
EVs are decoupling. Industry analysts expect used EV prices to fall 5-10% by late 2026 as federal tax credits phase out and cheaper new EVs hit the market. This is not yet fully reflected in the specific EV segments our AI forecasts, but it is a theme to track.
Trucks and SUVs stay strong. Our model is flagging more BUY signals in trucks than in sedans this week, aligning with wholesale data showing truck inventory tight and demand durable.
