Expert reviewers sort sports cars by more than horsepower, weighing comfort, value and everyday usability alongside speed. Kelley Blue Book’s scores run from a pricey grand tourer at the bottom to a Corvette and three Porsches at the top. Here are twelve sports cars, ordered from the lowest rating to the highest.

1. BMW 8 Series: Lowest Score in the Group
At the bottom of the group, the 2026 BMW 8 Series earns a 4.1 out of 5 from KBB’s experts, the lowest score among its ranked luxury convertibles. Its starting price is $96,050.
A low score does not make it a bad car, since the same list simply holds stronger scorers. The cost is the sticking point, because a price near six figures invites comparison with rivals that rate higher for less money, as several entries below show. Anyone drawn to the 8 Series for its looks should weigh that score against what the same money could buy elsewhere in the ranking.
2. Nissan Z: Affordable but Middling
KBB rates the 2025 Nissan Z at 4.2 out of 5, fifth among its best coupes list, with pricing from $44,110.
Among the more affordable cars here, it pairs a middling expert score with a modest sticker. Buyers who prize traditional rear-drive character may still weigh it favorably, since a rating averages many priorities into one number and cannot capture every taste. For shoppers on a tighter budget, the gap between its score and the leaders is smaller than the gap in price would suggest.
3. BMW M4: Speed Without a Better Score
On KBB’s 2026 luxury convertible list, the BMW M4 scores 4.4 out of 5, with pricing from $83,550.
The score matches the far cheaper Subaru BRZ further down the ranking, which shows how expert ratings reward value and balance as well as outright performance. Extra money buys extra speed, but not necessarily a higher mark from the people who test these cars. The comparison also helps buyers decide whether a bigger bill is worth chasing, since the experts clearly did not treat horsepower as the only measure.
4. Subaru BRZ: Approachable and Cheap
KBB rates the 2025 Subaru BRZ at 4.4 out of 5 and says it ‘proves that there’s still room for an approachable, rear-wheel-drive sportster.’ Pricing in KBB’s coupe rankings starts at $34,380.
The BRZ ties the M4’s score at a fraction of the cost, which is the kind of result that explains the praise for approachable sports cars. A low entry price keeps the fun within reach of many more buyers than the luxury names above it. Few cars in this group make as persuasive a case that a driver does not need a huge budget to enjoy a well-balanced rear-drive chassis.
5. Acura Integra: Practical Sports Car
KBB’s 2026 sports car ranking gives the 2026 Acura Integra 4.5 out of 5, from $34,695.
A hatchback-style entry among coupes and roadsters, the Integra earns its place through practicality as much as pace. Experts tend to reward cars that can double as daily transportation, and a low price helps. The score lands level with the Mustang and Z4, which cost very different amounts. It is a good fit for readers who want sports car fun without giving up a usable back seat or trunk, and without paying luxury prices.
6. Ford Mustang: Muscle at a Bargain
Second among KBB’s best coupes, the 2025 Ford Mustang earns 4.5 out of 5 and starts at $33,915, according to KBB’s coupe guide.
That makes it the cheapest car in this group while still scoring in the upper half. A long-running nameplate and broad appeal help, though the score reflects the whole package rather than any single number, and trim choices can move the price a long way. Pony car fans looking for the best value in this ranking will find the Mustang hard to ignore, particularly at the base end of its range.
7. BMW Z4: Premium Roadster, Same Score
KBB rates the 2026 BMW Z4 at 4.5 out of 5, with pricing from $57,275, in its luxury convertible ratings.
Matching the Integra and Mustang on score while costing far more, the two-seat roadster shows that price does not buy a better expert mark. What it adds is open-air driving and a premium badge, which suit buyers who value those over the rating alone. Readers considering it should also look at the Porsche roadsters that score higher, though those start at a noticeably higher price.
8. Mercedes-AMG GT: A Six-Figure Contender
KBB’s sports car scores give the Mercedes-AMG GT 4.6 out of 5, with pricing from $100,100.
Priced above $100,000 at the start of its range, it earns its score on genuine strengths. Still, the Corvette later in the order beats it on rating at far lower cost, which frames the AMG GT as a luxury choice rather than a bargain. Buyers at this level are usually shopping for presence and craftsmanship, and the AMG GT delivers both, even if the scoreboard slightly favors cheaper cars.
9. Chevrolet Corvette: American Talent Wins
KBB ranks the 2025 Corvette first among its best coupes at 4.7 out of 5, saying it ‘has the talent to back up the looks.’ Prices in KBB’s best-coupe verdict start at $70,195.
An American sports car outscoring pricier European rivals is the story of this list. The rating also arrives at a price well under the Porsches and Mercedes that share its top-tier score or sit just below it, which strengthens the value argument. Few rankings of expensive performance cars end with a domestic nameplate near the top, which is why this result tends to surprise first-time readers.
10. Porsche 718 Boxster: Top Mark With the Roof Down
The 2025 Porsche 718 Boxster earns 4.7 out of 5, the top score on KBB’s luxury convertible leaderboard, with pricing from $76,895.
Open-top driving usually costs a roadster something in rigidity and noise, yet the Boxster keeps expert praise anyway. It shares the top mark with the Corvette and its Porsche siblings, which makes it a strong pick for buyers who want a convertible without compromise. Anyone cross-shopping the three 4.7 cars should note the Boxster is the only one among them that offers a folding roof as standard equipment.
11. Porsche 718 Cayman: The Hardtop Sibling
Within the 2026 sports car list, the 2025 Porsche 718 Cayman scores 4.7 out of 5, from $74,795.
The fixed-roof sibling of the Boxster, the Cayman lands on the same rating for a slightly lower starting price. Hardtop buyers get the same expert endorsement, and the small difference leaves the choice mostly to taste for open air. Both cars share the same mid-engine layout and the same reputation for precise handling, so the decision often comes down to which body style fits daily life.
12. Porsche 911: Priciest and Still Top Tier
Rounding out the order, the 2025 Porsche 911 earns 4.7 out of 5 in KBB’s sports car verdicts. At $122,095 it is the priciest car in this group.
Its score only matches cheaper Porsches and the Corvette, so the premium buys something beyond the rating, mainly prestige and a long engineering heritage. For many shoppers the lower-priced members of the top tier deliver nearly the same verdict. Even so, the 911 remains the benchmark many other sports cars are measured against, and a score at the top tier confirms that status.
