I'd be more wary about all the stuff you can't see from just walking
around it.
Ask if its had any new parts fitted to replace old worn out ones.
Calipers will need looking at as they will be on the verge of needing
a refurb unless they have been done along with suspension arms seizing
on the eccentric adjusters,
front cross members rot, radiators tend to suffer with age along with the
heater matrix, a/c rad, crank pulley, brake & fuel lines over the rear axle
need a thorough inspection
I personally wouldn't buy an old mkiv unless i could have it up
on a ramp and do a thorough inspection.
£1900 is pretty cheap but not if it you then have to spend £1k +
on it fixing the above items i mentioned and if you bought new
Toyota parts £1k wont be enough by a long way
