Good on you to keep it on the road. Those old Toyotas as you know were over engineered/built as they were entering a already established truck market in the USA. And they showed out with that little 4 cylinder work horse.
I had a 2006 Police Interceptor as my first car, bought it back in 2012 from a guy that got them straight from the police departments. He was up in Cumming/Gainsville area. Sorry but I can't remember the guys name, it wasn't jacky jones...
Absolute great car though, loved it while I had it, old...
