My '86 had basically been my DD for close to 20 yrs. 80-90 mile round trip commute to NYC. Recently turned 300,000 on it. Did one clutch replacement on it. Other than that, never had any issues with it. ( Except for the belt I tossed on it the other day. But that was due to my own fault. Dont leave the covers off while you are waiting to do a retension...)
Only bad thing about commuting with it , is the stop and go traffic, but you get oblivious to that after a while.
Overall, the only complaint I've ever had with it , is the lack of power it has. But now that the engine has issues, I might do a SBC conversion.
