LP640 Murci, Performante, Ariel Atom, Lotus Elise, Audi TTRS, a pair of Mustangs,etc.
I think you're conceptually correct: As manual Murcis rise, they create headroom for manual LPG's and may even drag them along. But you can still find them for 200k.The last 3 manual Pre-LP Murcis on BaT for $400k, $250k and $277K.
I am not saying what they deserve that but I think the days of finding a manual Murcie for $200k or below are long gone.
A rising tide floats all boats. Maybe one day the tide will go out, but that doesn't seem to be any time soon.
Ex: # 622, a 24k mile clean-Carfax '03, dealer advertised for 200k.
