Today we mark Ferrari Friday with two very special competition cars built by the Italian manufacturer. First up is this lovely 250 GTO, which was delivered new to Italy. It was subsequently sold to Swedish raver Ulf Norinder, who painted it in the national colours of blue and yellow. While the car was later re-bodied by Drogo for road use, it has more recently been restored to its original configuration. Owned by the same American collector since 2005, chassis 3445GT is one of very few GTOs that is still actively been used as can be seen in our 44-shot gallery.
The other great Ferrari featured today is a 512 M that had started life as a 512 S in 1970. Updated to M specifications in the spring of 1971, it was raced at Le Mans in both configurations by Ecurie Francorchamps. It was also raced in North American and even competed in a Can-Am race. Now restored to its 1971 Le Mans configuration, 1030 made a rare appearance at the 2015 Goodwood Festival of Speed where ex-driver Derek Bell's successful racing career was celebrated.

In addition to the high-end Ferrari supercars we featured earlier this week, RM Sotheby's online-only Driving Into Summer sale also includes three 1990s icons. One of our all time favourites and the last of the great Lancias is the Lancia Delta HF Integrale Evo 2. It is the ultimate development of the road-going Deltas and was introduced when Lancia had already withdrawn their Group A works team from the World Rally Championship. Although in production for a single year, around 2,500 examples were built. The consigned car was sold new to Japan and has only recently been imported into the United States.
Although in this case for DTM touring car racing, the Mercedes-Benz 190 E 2.5-16 Evolution II was also built to homologate a Group A racer. Like the Delta, the example on offer this week was sold new to Japan and was more recently shipped to North America.
Another production road that was hugely successful as a Group A racer in the early 1990s was the Nissan Skyline GT-R. It became a legendary machine for so many other reasons and can only be imported into North America for a couple of years. That also happened to the Cherry Red car that is consigned to the RM Sotheby's auction. It boasts some mild modifications and accordingly can be yours for just $45,000 - $55,000.
Bidding on the Delta will close on Friday, while parties interested in the Mercedes-Benz and the Skyline can still place their bids until Saturday.

With conventional auctions still out of the question, RM Sotheby's stage their Driving Into Summer online only, time based sale this week. The lots opened for bidding on Friday and will close on the 28th or the 29th. The sale is headlined by the trifecta of Ferrari supercars of the 1980s, '90s and '00s. The earliest of the trio is this 288 GTO, which was delivered new to German collector Hartmut Ibing, who also had a 250 GTO in his collection. It was briefly stolen when it was brand new and has only three legitimate owners. The GTO is estimated to sell for $2.2 - $2.4 million.
From the 1990s comes this F50, which was also sold new to Germany. It was the second chassis built and was shown at the 1995 Frankfurt Motor Show. During its 25-year life, the $2.5 - $2.75 million F50 covered just over 3,000 miles.
The Ferrari Enzo consigned to the sale has had only two owners from new and is almost brand new with the odometer reading 1,250 miles. Delivered new to San Francisco, it is estimated to sell for $2.6 - $2.9 million.
Over the weekend, Radical introduced the SR3 XX, which is a more sophisticated version of the British sports car's familiar machine. It features an all-new electrics system that has been developed by AiM Technologies. The top-of-the-range SR3 XX is powered by a 1.5-litre version of the Suzuki Hayabusa engine, which is good for an impressive 226 bhp.

Two years ago, Nissan and Italdesign Giugiaro announced a collaboration to celebrate the 50th anniversaries of the iconic Nissan GT-R and Italdesign Giugiaro. A limited production run of 50 Italdesign bodied GT-Rs was announced and a first prototype was shown. Now, the first production GT-R50 has been revealed. It is based on the Nismo version of the GT-R, which houses a 710 bhp, hand-built version of the familiar twin-turbo V6 engine. In keeping with the theme, the GT-R50 is limited to just 50 examples and deliveries will start later this year. The car is not quite sold out yet, so you can get your own if act quickly!
Maserati, meanwhile, had a major release scheduled for Wednesday but this, sadly, had to be postponed due to the global COVID-19 pandemic. The car in question was the upcoming and highly anticipated MC20 mid-engined sports car. The launch has now been pushed back to the fall but Maserati did release some additional teaser pictures of the MC20 test car, which has been dubbed the Stirling Moss in memory of the former Maserati works racer, who passed away last month.
German BMW enhancer Alpina have worked their magic on the latest X7 to create the American-market-only XB7. It features BMW's well known twin-turbo V8 engine that produces around 600 bhp in this application. Alpina have also reworked the suspension and fitted the XB7 with an opulently appointed interior.

Sadly, it has become a familiar feeling but we should have been packing our bags today for the next great event. On the schedule this weekend would have been the annual Spa Classic. Whereas some events have been postponed to a later date, the Spa Classic has been cancelled for 2020. To illustrate why this is such a shame, we have taken a closer look at three great machines that participated in last year's edition.
Competing in the Endurance Racing Legends series was this Aston Martin DBR9. It is the second customer car built and was entered for just one race in period. Due to an engine issue, it actually did not take the start in its single outing. Still fitted with the massive rear wing it was allowed to run with in Brazil, chassis DBR9/102 is now being raced with great verve by a German enthusiast.
While Lola built 22 T212s for the 1971 season, only the example featured today was raced at Le Mans in period. It was campaigned that year by Guy Edwards with considerable success. Sadly HU26 failed to finish at Le Mans due to a flywheel failure.
The Greatest's Trophy race saw a German enthusiast campaign this Porsche 718 RS 61. It was sold in period to an Austrian racer, who was quite successful with the car in hill-climbs. Between the late 1960s and 2000, it was seen in public only once and accordingly 718-075 has survived in highly original condition.

In time for Summer, Porsche have revealed the third body variant of the new 992-generation 911 in the form of the Targa. Available from the launch with all-wheel drive only, the variants available are the 379 bhp Targa 4 and the 444 bhp Targa 4S. Both are equipped with a fully automatic Targa roof that can be opened or closed in just 19 seconds. Needless to say, both the Targa 4 and 4S are faster than their predecessor and can be specified with optional ceramic disc brakes.
Having a foldaway Targa roof is nothing new as is demonstrated by the unique Ferrari 308 GT Rainbow. Designed by Marcello Gandini and built by Bertone, the 1976 Turin show car served as the carrozzeria's pitch for the replacement of the 308 GT4 Dino. It is built on the same underpinnings and features a striking wedge-style body. The roof features a hinge at the back that allows it to slide down behind the seats. In the end, Pininfarina got the job, so the Rainbow remained a fully functional one-off.
