The first owner was Jack Henderson of Denver, Colorado. He kept this 911 for 18 years/95k miles. He serviced it regularly at either the local Porsche dealer or an independent specialist. He kept not only every service receipt but also had the maintenance booklet stamped. This is one of the first maintenance booklets I’ve seen stamped from new until the present day.
On March 4th, 2004, with 95,068 miles, Jack sold his 911 to Dave Bertrand from Brighton, Colorado. Dave enjoyed this 911 for 5-years and added an additional 18k miles. He had always wanted to build an RS conversion and was particularly interested in doing a backdated project. By 2009, the original black paint was showing some age so the long and fully documented endeavor began. He planned on using the stock drivetrain especially since he had just rebuilt the original 915 transmission. Also, the suspension was recently refurbished and a completely new factory wiring harness was installed (over $7,000 in 2005 dollars). The main focus was the steel backdate body. A year later, the project was completed in the Porsche factory color Oslo Blue. The work was done by one of the top shops in Denver. Dave reassembled the car on his own as a project (fully documented on Pelican threads). The car was finished with an RS look complete with ducktail and front/rear fiberglass RS bumpers from Getty Design. The front conversion was done with correct factory steel parts (hood and front fenders) to retain that original/correct look. The interior was still fairly stock as were the mechanicals.
Shortly after the project was finished (2011), a texting teenager ran into the car at an intersection near his home. Although the damage was fairly superficial, Dave decided to do the build even better than the first build. The same paint and body shop re-did the entire body. It was stripped down to the bare metal and everything was completed at a much higher level. King of Trim refinished all the bright work to its proper early finish.
Later that year, when the car was re-finished for the 2nd time, he decided to sell the car to a Porsche friend of ours from Wyoming on September 11, 2011, with 120,327 miles. This owner has joined us on many vintage car tours over the past decade. He is a long-time Porsche enthusiast who was looking for the perfect car to use for vintage touring events. He wanted something that looked the part but would be practical enough for long drives since he would be driving it from Wyoming to wherever the start of the event took place.
Shortly after he bought this Porsche, he began thinking about upgrading the engine. The engine was still original with 125k miles and never touched. He ended up connecting with Ed Mayo, owner of Mayo Performance in Euless, Texas. Ed had recently built a 3.2 Carrera motor for one of his clients who, unfortunately, totaled the car by running into a donkey at 80mph. The engine was pulled because it was a front-end collision and the motor was fine. It only had 15,000 miles on it since Mayo finished it.
Some details of the Mayo engine build include:
Top end overhaul
New valve guides
ARP rod bolts and head studs
New rod bearings and rings
964 Cams
Backdated exhaust system
Stainless SSI heat exchangers

The end result was a great balance of both power and reliability. The engine has a bit more throttle response than a stock Carrera engine. During this engine swap, he upgraded the suspension system as well as the heating and air conditioning system, which were extracted from the donor car. The A/C system had just been rebuilt and upgraded to handle the brutal Dallas summers. With the bigger ’86 dash vents, the car cools down quite nicely. The system Mayo installed was a Kuhl retro A/C package with upgraded front and rear condensers as well as an improved compressor with a new receiver drier. All the lines were upgraded for the R134a conversion. It’s not the same level as you expect in brand-new cars, but it is quite impressive for a 40-year-old car and much better than it was when new.
Lastly, the interior was updated to a more RS-look with RSA door panels, reproduction sport seats (since have been replaced), and RS lightweight carpet with rear seat delete. Shortly before we sold it for this owner, the fuel pump was replaced with a fresh Bosch unit.
On September 12th, 2014 with 136k miles, we helped this owner sell his Oslo 911 to the current Orange County owner. The current owner is a long-time Porsche enthusiast who has a large collection of new and old Porsches that’s always changing. This owner purchased this 911 for the same purpose as the prior owner – vintage touring events. For the past decade, the current owner has added another 10k miles of local car events and a couple of Targa California rallies. Although this 911 has been a fun Porsche to use on these events, the current owner is going to be participating less and wants an early car to take to shows. During this owner’s tenure, they were as fastidious as the previous owners. Most of their routine services were performed by Haydon Bros. in Anaheim, California. They also used Joey Seeley of E-Motion Engineering in Costa Mesa, California for suspension improvements. Highlights of recent maintenance include:
