ive got a similar question to ask, how long is a piece of string?
.

as above really.
i got my 1996 1.3 SR for £250, needed £20 spending on it and a bit of welding, but 2002 micras can go for well over £1000.
ive seen 1989 K10 micras sell for almost £3000,
the point im making, is price depends on condition, spec, mot, tax, etc etc.
