Lot PEX3712: 2020 Porsche 718 Boxster Spyder

Great question! The Porsche 718 Boxster Spyder and Cayman GT4 are practically twins under the skin — they share the same sublime 4.0L naturally aspirated flat-six from the 911 GT3, the same 6-speed manual transmission, and nearly identical suspension tuning. Think of them as two flavors of the same incredible driver’s car!

What’s the Same

• Engine: 4.0L naturally aspirated flat-six (414 hp in this 2020, bumped to 420 hp in 2021+)
• Transmission: 6-speed manual (both can be optioned with PDK)
• Chassis: GT4/Spyder-specific suspension derived from the GT3, with way more aggressive geometry than standard 718s
• Performance: 0-60 in ~4.2 seconds, top speed ~187 mph (Spyder) vs ~189 mph (GT4)

The Key Differences

Body Style & Weight

• Spyder: Convertible with manually-operated roof, iconic twin-bubble rear fairings — pure open-air driving
• GT4: Fixed roof coupe with a proper rear wing and more aggressive aero
• The Spyder carries roughly 50–70 lbs extra for the convertible mechanism, while the GT4’s fixed roof adds structural rigidity

Character

• The GT4 is the sharper track tool — more aero grip, slightly more focused feel
• The Spyder is the purist’s roadster — sensational noise with the roof down, classic Porsche Spyder heritage

Market Reality Based on our Classic.com data:

• Cayman GT4 Manual: Currently averaging ~$120,200, with 20 for sale right now. Recent sales range from $79K–$169K
• Your Spyder: At $124,990 with 26K miles, it’s priced right in line with comparable GT4s

Interestingly, the 718 generation flipped the traditional Porsche script — the Boxster Spyder commands a small premium over the Cayman GT4 at MSRP, whereas historically the coupe was always pricier!

Can’t go wrong with either — choose the GT4 if you want the sharpest track experience, or the Spyder if you value that open-air, analog driving experience. Would you like me to find some Cayman GT4s for you to compare directly? Or can I help you with anything else about this Spyder?
