I will be purchasing a 308 in the next 6 months. Unfortunately, I grew up driving 250's, 365's, etc., but I don't have the funds. In any event, I've driven Quattrovalvole's and earlier injected cars; I haven't driven a carbeurreted 308. Since I won't be doing any major service myself, should I just stick with 1983 or newer, or can I consider the 1977-1980. SCM has me all confused..
