I bought a tired Sierra with the front already ripped. You can imagine how my wife was happy with this sight outside during most of the winter.
Had some fun tearing it down in -10°C temps this past winter. Not too bad when all the rusted suspension nuts keep you constantly working hard.
Eventually I scrapped the shell and got some beer money after the VAT, transport and deregistration costs were counted out
Initially I though of using the Pinto that came with Sierra
but later I was persuaded to use a Zetec. Either with standard pre-PATS ECU or MegaSquirt (I'm looking forward to all the soldering, electronics are fun)
