A 535i with a manual transmission is probably the third most desirable version of the E34 5-series, after the M5 and the 540i/540i M-Sport. These cars came with the 3.5 liter “big six” M30 engine (technically a 3.4 liter mill) and represented the top of the non-M lineup until they were replaced in 1993 by the V8-powered 540i. While manual 540s are a hoot if you can find them, they are not without their faults (somewhat thirsty, and susceptible to the nikasil issue, in which the sulphur content of 90s era gasoline had the tendency to eat away at the nikasil lining of the block, requiring a replacement engine). The six-cylinder manual 535 on the other hand, which is perhaps even harder to find than a manual transmission 540, is torquey, smooth, reliable and fun to drive while returning decent fuel economy.
