MINI Cooper trim comparison
2026 MINI Cooper S Signature vs S Signature Plus
The Cooper S Signature starts at $33,800 while the S Signature Plus is $40,300. That $6,500 gap buys 3 meaningful differences.
$6,500 more is ~$115/month. The question is whether the added equipment will matter to you every week.
The S Signature is the cleaner stopping point if keeping roughly $115/month in your budget matters. The S Signature Plus earns the extra money only if you want the nicer equipment factory-installed and under warranty.
Think about this as a monthly tradeoff, not just a sticker gap. The S Signature Plus adds about $115/month on a typical 60-month loan, or around $6,900 more overall with interest.
