Type 40 TARDIS by || Times played:19
The last Type 40 TARDIS in existence was quite recognisable when it was first stolen, its engines sounding harsh and heavily worn. Even the dimensional stabilisers could be harsh on the ears when stepping across the threshold between the outer doors and the inner doors.
It seems to have had at least three engine upgrades since those days, giving a cleaner, smoother sound. The dimensional space between the doors has been completely removed, blending the inner and outer dimensions more smoothly but resulting in the doors becoming completely useless in cases where the outer dimensions are leached or destabilised. Clearly this old TARDIS has been renovated by an amateur.
