I haven't seen any 914s, not even a 914-6 but there are tons of 911s crossing the block. Cheapest one has been about $150,000 and they go way up from there.
Years ago they talked about how undesirable the Dinos were. Not real Ferraris they said. Worth real strong money these days, bolstered by their expensive relatives.
How long before we see four cylinder 914s at 100 grand? Ir will happen at some point. My guess is it will be a tidy 2.0 liter or perhaps one of the very early ones.
