The 720S Spider paired McLaren’s carbon Monocage II chassis with a retractable hardtop, and this one has covered few miles. It carries carbon ceramic brakes, forged wheels, an active rear spoiler, dihedral doors, power bucket seats, and navigation. Bidding stands at $105,000 with six days remaining and two bids placed.

What it’s worth right now
Data from Kelley Blue Book sets the 2020 720S Spider Fair Purchase Price at $241,000. Dealer listings include a 5,027-mile example at $249,900, a 3,915-mile car at $279,590, and a 16,974-mile Spider at $227,800.
The modifications place this one below stock examples. The 6,000 miles, single ownership, and Performance specification help, while the aftermarket tune and downpipes, uncertain warranty eligibility, the lien, and minor blemishes temper the number. Fair value lands between $205,000 and $245,000, with $225,000 most likely. The current bid of $105,000 has six days to run against a reserve.

Condition and details
The specification is complete. The car wears Memphis Red with a retractable hardtop, dihedral doors, a splitter, a diffuser, and an active spoiler with air brake, and it rides on 19-inch and 20-inch forged wheels with Pirelli P Zero tires and carbon ceramic brakes. The dealer reports paint protection film up front and blemishes on the right mirror and beneath the front bumper.

The drivetrain has been modified. The dealer states the M840T V8 carries an aftermarket ECU tune and downpipes, and the modified output is not specified. Because of the downpipes, a buyer should confirm the car will pass emissions in their state. A tune can also affect eligibility for warranty and extended coverage, so a buyer should confirm with McLaren.

Paperwork needs attention. Inside are black leather and Alcantara buckets with red stitching, memory settings, dual-zone climate control, and navigation. The Carfax is clean, but a lien must be paid before the Florida title transfers, and the dealer charges no fees. A pre-purchase inspection from a McLaren specialist should check the tune, the hydraulics, and the roof mechanism.

What makes the McLaren 720S Spider unique
The 720S Spider brought McLaren’s 710-horsepower supercar into open-top form, using a carbon fiber Monocage II that needed no extra stiffening for the roof. Its retractable hardtop, dihedral doors, and hydraulic suspension made it one of the most capable convertible supercars of its era.

Stock examples hold value best. Modified cars appeal to enthusiasts seeking more power, but tunes can narrow the buyer pool and complicate warranty coverage. Low-mileage, documented cars command the strongest prices.
My take
At $105,000 with two bids and six days to run, my call is $225,000, with $245,000 possible if bidders value the low mileage and Memphis Red finish. What makes it compelling is the performance, since a 6,000-mile 720S Spider with carbon ceramics and an open roof offers staggering speed. What tempers it is the aftermarket tune, the emissions and warranty questions, and the lien. Confirm warranty eligibility with McLaren, then bid.
