Here lies my small collection of information in regards to this specific model of 3-series.
General
The E30 was produced from 1982–1993 in a variety of body styles: Coupe, Sedan, Convertable, and Touring. There are two major revisions of the car, most commonly referred to the early-model, which was produced up until 1987/88 and the late-model, which was produced from 1988 up until the car's discontinuation in 1993.
Specifications
For my personal vehicle, it's equipped with the following:
| Model | 1990 325i Coupe |
| Color | Brilliant Red |
| Engine | M20B25 |
| Transmission | Getrag 260 5-speed manual |

The options are my best guess based on available options in Germany—I don't actually have a buildsheet and haven't visited a dealer to see what my car came with. It's a USDM car so chances are that some of the codes are different and there are probably some things that I don't even know were options.
