BMW E36 Chassis Numbers

The chassis plate on BMW is located on the left-hand door sill and shows the name of the company who built the shell, i.e. who installed the roll-cage. Though the 1980s and early 1990s construction of most shells was contracted out to German company Matter.

For the E36 3-series built during the early 90s, chassis numbers were in the format E36/XXX NNN YY

The number is usually 3 or 4 digits in length with an extra leading zero, so 070 or 0124 instead of 70 or 124. It's believed there were a total of either 128 or 129 cars built, which includes all specifications.

From 1995, production of the shells moved in-house to BMW Motorsport.

For these later cars, chassis numbers were in the format E36 XXX YY/NNN
In this case the specification code of STC was used to indicate FIA SuperTouring. Unlike the earlier cars, the sequential number is year-specific, restarting at 001 each year.
