1968 Maserati Ghibli Coupe s/n 115-652, an unusually user-friendly example of the iconic 60’s era Italian supercar. Maserati Ghibli Coupe s/n 115-652 has had only two owners in the last thirty-eight years, and was restored by Claus Groth. Claus had it stripped and painted, the engine was rebuilt and Claus did the meticulous finish work and assembly. Claus Groth was well-known in the Maserati world for being a diligent and accomplished engineer for the Maserati cause, solving many design flaws and missing-parts issues. As just two examples of his dedication, Claus published an updated electrical circuit diagram which is orders of magnitude better than the version in the Factory manual, and that is still offered for sale by MIE, based on this very Ghibli. Additionally, the current owner still has engineering drawings of the windshield wiper bushings Claus had made at local machine shops. The current owner also has the compiled Ghibli information binder with part numbers, exchanges, drawings for unobtainable parts Claus Groth had made and other information. In 1997, Ghibli s/n 115-652 was sold to the current owner, an engineer who has lovingly maintained it for the last two decades. Ghibli 115-652 has been shown at Concorso Italiano a dozen times in the past 20 years, and has been across the stage at Concorso twice to win awards, plus double enteries at both the Hillsborough Concours twice and the Palo Alto Concours.

Ghibli s/n 115-652 is finished in period-correct Alfa Rosso Amaranto (Burgundy metallic) with black leather, and is fitted with the elegant Borrani wire wheels, the original ZF five-speed gearbox, power steering and A/C. The twenty five year old paint is in amazingly good condition except for the usual very minor stress cracks where the rear glass meets the roof line. The body is very straight with excellent panel fit and the doors close like Italy’s answer to a Swiss vault. The hood, the front bumpers and lights, the rear deck and rear lid all fit as new and all glass and chrome are in excellent condition. The frame, the floor pan and all lower panels are rust, dent and damage free. The black leather interior and black carpets have an excellent patina with only minor surface wear and compression due to use. The seat bolsters remain full and firm. The dashboard features an expansive array of instruments and a wood trimmed wheel. The top dashboard surface is finished in a contrasting fabric material consistent with the original specifications. The center console houses the original Becker Mexico radio.

Under the hood, the very nicely finished 4.7 liter quad-cam engine is nicely sorted and has been restored with the correct factory finishes, including proper hosing, wrinkle finish cam covers, proper air cleaner paint and correctly bundled hoses. As yet another illustration of Groth’s attention to detail, in the info-binder there is a paint-code for the deep red Trident emblem in the middle of the airbox. The engine fires to life quickly, with an excellent raspy punch. Power in all gears is quite impressive, delivering on the torque promise of the race-bred engine. The ZF gearbox is smooth and reliable, the 4.7 liter quad-cam delivers acres of torque at low RPMs and willingly uses all four Weber carbs to deliver a very strong top end. The suspension and brakes have been sorted out very nicely, so Ghibli s/n 115-652 is a pleasure to drive in city traffic or the highway. Comes with the original tools, tool roll, jack and jack kit plus an MIE reprint of the owner’s manual, the parts manual, the service manual, the electrical system schematic and the information binder compiled by Claus Groth.
