Actually the 308/328 series cars were the last ones produced by Ferrari that could be serviced by a non Ferrari trained, albeit competent, mechanic. With the introduction of the 348 came propreitary electronics that can only be serviced with equipment found at a dealer.
The 308/328 had simple Bosch fuel injection, a go/no go electronic ignition and the engine doesn't have to be pulled for routine service.
$18k is a great deal. Private sales of early 308's are hovering at ~$22-27k for a clean, unabused example. An '85 308 QV will bring $32k.
