This 1989 BMW 325i Touring is believed to be one of four cars converted by Rossiters Ltd. in England to AC Schnitzer ACS3 specification, and the seller states this car is one of the first ACS3 cars built and the only RHD wagon. Work performed in 1991 included a right-hand drive conversion as well as the installation a modified version of Schnitzer Motorsport’s hand-built 2.7-liter inline-six touring car engine, an ECU, exhaust system, limited-slip differential, and more. The car was imported into the US in 2014 before being purchased in 2015 by the seller, who believes this to be the only example in the US. Finished in red over black leather, it is equipped with a 5-speed manual transmission, a sunroof, an Alpine stereo, Brembo brakes, and more. This Touring is offered with spares, service records dating to 1991, literature, documentation from AC Schnitzer, a cover, a Carfax report, and a New Mexico title in the seller’s name.

The car was converted to AC Schnitzer S3 specification in 1991 by Rossiters, reportedly when it showed 18k miles. The seller believes that four cars were converted in the UK, with Rossiters stating this example is the only wagon. Exterior additions at the time included side skirts and badging, while AC Schnitzer valances were added at a later date. A repaint in red is said to have been performed under previous ownership following rust repair, and a new windshield was fitted. Photos of additional rust repair conducted during the seller’s ownership are available in the gallery below. Remaining corrosion is noted near the left rear taillight.

ACS Type 1 16″ lightweight wheels were added as part of the conversion and refinished with body-color trim rings during the seller’s ownership. New 205/50 Yokohama rubber was mounted in July 2015. AC Schnitzer springs and shocks were reportedly installed as part of the initial conversion. Fresh Hawk Performance brake pads and Brembo rotors were fitted and a brake fluid flush was performed in 2015.

The interior is trimmed in black leather over factory sport seats and features a sunroof and an aftermarket Alpine stereo. A new graphite knit headliner was installed during the seller’s ownership along with a Husco armrest and an AC Schnitzer e-brake handle, steering wheel, pedals, and floor mats. A seam failure is noted on the driver’s seat, as are tears on the door panels. The rear cargo net and cover show wear, and the right rear seat’s flip-down function is said to work only on occasion.

The car was converted to right-hand drive while in the UK and features instrumentation including a 150-mph speedometer and a 7k-rpm tachometer with an AC Schnitzer emblem. The 6-digit odometer shows 136k miles, about 2k of which were added by the seller. The seller reports that the fuel gauge works sporadically and that the coolant warning light has remained on since the last service.

The 2.7-liter inline-six was reportedly handbuilt by Schnitzer Motorsport and is said to include a bored E34 block, a billet crankshaft, forged connecting rods, flat-bottom Mahle pistons, a ported and polished cylinder head, an ACS camshaft and valve cover, and aluminum motor mounts. Shifting is through a 5-speed manual transmission. Equipment installed at the time of conversion included an ECU, exhaust system, and limited-slip differential. Service in the last two months is said to have consisted of a new timing belt, tensioner, valve cover gasket, and spark plugs as well as a valve adjustment, oil change, and power steering flush. Compression and leakdown tests were performed at this time as well, the results of which are available in the gallery. Other service during the seller’s ownership reportedly included:

2017 – New engine mounts

2016 – New fuel pumps and lines

2015 – New water pump, fan clutch, thermostat, intake boot

The seller reports that the wheel wells and underside have been cleaned and treated in an effort to prevent corrosion. An oil leak was recently fixed by the seller with new rings, pressure valves, and washers. Multiple welded repairs are noted under the rocker panels and side skirts, additional photos of which are available in the gallery below.

Spares included to convert the car back to left-hand drive are included in the sale and consist of an appropriate dashboard, under-dash trim, glove compartment, center console, rack and pinion, and power steering lines. A set of rebuilt Bilstein shocks is also included.

Assorted literature, documentation from AC Schnitzer, a car cover, three keys, an AC Schnitzer key fob, and service records dating to 1991 will be provided with the car. More information regarding the AC Schnitzer S3 conversion is available in a document that has been provided by the seller in the gallery, as is communication between the seller and AC Schnitzer.

The first entry on the Carfax report is from August 2014 when the car was imported to the US, according to the seller. An “Exceeds Mechanical Limits” title was issued in New Mexico in March 2015 and is said to be the result of the seller receiving a mileage-exempt Florida title from the prior owner.
