      Is the speedo that far off? The needle is damn close to 150.

                    E30 factory spec is +2.4mph PLUS up to 10% of actual speed. German (EU actually) law that speedometers must read high
                    The first car I ever rode in was an e30

                      Count it as 10% overall and you're probably safe. Generally, I think speedos that read high are great, we feel like we're going faster while we save fuel and are less likely to get a ticket.
