I have owned several & they all were reliable, however they do require more maintence than other models due to adjustable valves. ALSO they are somewhat oil leakers!
The last one that I had was a euro 1981 280E that made 200+ HP. & was a blast with a manual transmission. I autocrossed the car for 3 years & won several local awards in SCCA.
