The e36 has a lot of places for gauges in the dash, at least 6 if you relocate/remove the OBC, more if you remove the center vent, radio, etc.
There are also dual display gauges to help conserve space.
"Driving is like a narcotic, an addiction that can take over lives. It ruins people, breaks families apart, and even kills. Itís habit that needs to be fueled. Time, money, rationality, sweat, knuckle skin, and anyone who disapproves are of little importance to a driver, and are often overlooked. Hi, Iím Nelson, and Iím a drivaholic."
