"The feeling of summer driving a car from the forties with a straight-eight is a very special feeling."

Description

The current owner bought the car on Ebay in the spring of 2005; it came from Washington State, north of California. At that time the car had covered just over 74,000 miles, equivalent to 118,000 km, probably correct, and today the odometer has turned up to 86,819 miles. Reportedly, there were not many options to choose from once the model and engine type had been selected. XLF016 has, in addition to the larger engine and automatic gearbox, also the more expensive "De Luxe" radio and most likely an original General Motors gangster cap that fits the car perfectly. The seller is said to have been the third owner of the car. The current owner works with technical information and has written down everything he knows about the car. We will therefore let him describe its condition under Technical, Exterior and Interior.

Condition

  • Mechanical condition

    The drivetrain is largely untouched. The engine can be a bit uneven right after startup but then feels strong and runs well, though it would still benefit from a thorough service. During my years of ownership, it has received regular light servicing (oil + filter) and new ignition parts at some point. A more comprehensive overhaul has constantly been planned, but everything has worked so well that it never happened.

    The engine leaks a little water from a drain cock on the block, which looks unfortunate but is actually an easy fix.

    The Hydramatic automatic gearbox received new fluid at the time of purchase. Since then, I have only checked the level, and it shifts smoothly and nicely.

    The shock absorbers leak a little, mainly the rear ones. I have topped up the oil every few years, and that has worked well. Otherwise, the undercarriage has light surface rust and traces of oil leakage here and there, but nothing alarming.

    At some point, the car received an undercoating treatment, but it has long since dried out and partially flaked off. Overall, the car looks a bit dull underneath but is sound and more or less untouched.

    Chassis lubrication has been performed practically every year. The car is free of play and rattles and feels reasonably stable on the road.

    A voluntary inspection was carried out around 10 years ago, passing without any remarks, but unfortunately it is not documented.

    The car is fitted with 7" wide chrome 15-inch American Racing Smoothie wheels in fine condition. The tires, Coker Classic L78-15 4" WW, were mounted approximately 10 years/2,000–3,000 km ago.

    The car also comes with the original wheels with trim rings and hubcaps in fine condition, with dry tires.

    Shortly after purchase, I replaced the right rocker panel trim and the stone guard at the front edge of the right rear fender with NOS parts, as they were scraped and scratched. I also replaced a couple of lamp lenses, some gaskets, and minor rubber trim. I also bought a trunk light on eBay since it was missing.

    In addition, I have imported two identical cars and taken some parts from them. Mostly small items, but also the corner pieces for the front bumper, which were in great condition on one of those cars and somewhat scratched on XLF.

    The brakes were overhauled a couple of years ago, and the car has barely been driven since. At that time, the master cylinder, all brake shoes, and the front and rear brake hoses were replaced, and the wheel cylinders were rebuilt.

    In the summer of 2023, a new Optima 6V battery was purchased. The cover that originally sat over the battery does not fit the new battery but comes with the car.

  • Interior condition

    The interior is original and is becoming dry and worn. There is a tear in the driver's seat, minor wear on the front door panels, and the seam on the top of the rear seat backrest has come apart. I have kept blankets on the seats all these years, and with them it has looked perfectly fine. In recent years, the rubber mat at the front around the pedals has also cracked and small pieces have come loose. The headliner is intact and in fine condition, and the steering wheel is in near-new condition. The weatherstripping in the doors etc. is generally in perfectly acceptable condition. All gauges work, though not the radio or the clock, and I have not investigated why. The wood-grain trim on the dashboard is damaged by leaking water in a couple of places. The windshield washer system is complete but not connected. All door handles and window regulators work perfectly both outside and inside. All locks are original and work well, and spare keys are included.

    The trunk is in good condition with the cardboard panels and the original mat intact. The original jack as well as the spare wheel holder and the special hubcap are also in place.

  • Exterior condition

    The car is largely in original condition but has been repainted in one of the two green shades it originally had. At that time, more metallic flake was also mixed into the paint. It is unclear when the car was repainted, probably at least 25–30 years ago.

    There is a minor rust spot at the rear edge of the left front fender. It was already there when I bought the car and has not gotten noticeably worse during my ownership.

    A few small rust bubbles have also appeared at the lower right of the trunk lid, but fundamentally the car's sheet metal is sound and unwelded as far as I know.

    The cover panel between the body and the rear bumper has at some point taken a knock, and the paint has cracked there. It sounds worse than it is and has not deteriorated during my 20+ years of ownership.

    The paint is not perfect but is of good quality and now needs a polish to bring back the shine. The chrome is generally really nice, though not perfect. There is very little surface rust in a few spots, which I have kept in check with polish on a regular basis.

    The top grille bar was dull at the time of purchase and has been rechromed here in Sweden. Above all, the cast chrome parts – for example the front fender trim, handles, and wiper towers – are in fine condition, and these are parts that are difficult to rechrome with good results.

    Some trim pieces are made of stainless steel and have also held up well.

    The car had no turn signals at the time of purchase, so I have added them. At the front, they are built into the bumper guards as original. At the rear, small turn signal bulbs are fitted in place of the reflectors in the taillights.

    They are not very visible in daylight and should be updated. However, they passed inspection.

    A master cutoff switch has been mounted on the firewall and can be reached from inside the car.

  • General condition

    The overall impression spells a kind of hard-wearing original condition with a handsome exterior, an untouched interior and, most of all, a cool unrestored, surface-rusted and coolant-dripping inline eight with a sound all of its own. If it ain't broken, don't fix it is a good truth in most cases, and so it is here.

Facts about the model

The Oldsmobile Dynamic Series 78 was the mid-range model of the three series 60, 70, and 90. For 1948, the 90 series received the all-new pontoon body style, while the 60 and 70 series retained the old rounded shapes. The small 60 model shared its body with its sibling models from Chevrolet and Pontiac and had a wheelbase of 119" and a "break" between the roof and the trunk lid. The Series 70 had a wheelbase of 125", a longer rear section in fastback style, and rear bumpers that extended considerably further forward along the sides. The largest model was only available as the Series 98, where the eight indicates the number of cylinders. The other series were available as both 66/68 and 76/78, meaning they could be had with either a 6 or an 8. They came with a manual gearbox as standard but could be ordered with the then relatively new four-speed HydraMatic automatic transmission. The 8-cylinder flathead engine displaces 257 cubic inches (4.2 liters) and produces 110 hp.
