MVC OTP article:  Written with the aid by Peter Liesenkloss, type 170 representative MVC and Egon Thiel, district police authority Neuss Translated by Volker Nahrmann

The 170 D OTP are principally painted in a matte or glossy green, --- Berlin police force had theirs painted in blue , while the police force of Baden-Wuertemberg had green with black fenders. Always without chrome plated trim --- sometimes however with aluminum runningbord trim or chromed radiator shroud, lamp rings, door handles and hinge bolts. This should guarantee that there are no contentious detail questions about its visual features. Since the OTP already had the Hypoid interlocked rear axle and wider track of the second revision stage (170Db),  both running boards and rear fenders were wider. The 4" wheels with 6,00-16 tires were also unlike the normal series (3.5"/5,50-16). The rear axle was equipped with an auxiliary spring within the normal spring. A tow-hook in front and in the back at the frame distinguishes it as a "workhorse". It can be said with certainty that no OTP was originally sold to a private buyer, although many might have  found it attractive at the time. Only after being taken out of  government service could they, as still possible today, while robbed of all their official emblems, be sold or auctioned off. At the time they were available at prices that allowed even university students to purchase such cars. It is thanks to these students that many 170 Diesels escaped the junk yard. The OTP was therefore surely the cheapest way to drive an open Mercedes. Today  these cars in drive able condition are not available for 150, - Marks anymore. But in the comparison with its gasoline powered colleagues of the170 S series an OTP is not only lower-priced in the acquisition, but also in maintenance and restoration. The interior equipment is it nearly completely devoid of chrome, trim and accessories and the upholstery is out of vinyl instead of leather. The body work, however is just as complex as on a 170S Cabrio A. The 170 D OTP possesses four doors, which are all fastened to the b-column. So that the car does not break apart, if one opens more than one door, the right and left b-columns are connected by a tubular structure with one another and the floor panel. This frame stands out above the back rests of the front seat.

It also served a place to hand cuff suspects while in transport. This bracing limited the rearward movement of the front bench. Shifting of the front seat is thus not possible. The OTP like a true tourer has a single layered top and a roof frame without stiffening profiles. The advantage of this is that one can fold the entire folded top up very small. The disadvantage in the comparison to the Cabrio is that there is no thermal insulation within the roof , that from the interior one looks directly at the top frame, and with out the padded layer it is almost impossible to achieve an elegant roof line. The back window is just like all the  other open cars, only a "shooting hole" and serves more to let little light to the inside than granting a view of the rear roadway. The OTP had no carpet and in contrast to the sedan it has a  rubber floor mat in the rear that covers the tunnel to avoid damages by the work boots.
