About ETX Alien Infiltrator

ETX Alien Infiltrator (7646-1) is a LEGO Space set released in 2008, currently averaging $70.95 used on BrickLink. It comes with 4 minifigures worth a combined $14.88. The set has retired from retail, so secondary market is the only option. The full parts inventory runs 122 pieces.

Part-out value

The minifigures account for about 21% of the set's value ($14.88 out of $70.95). The remaining value is in the parts and the set as a complete package. Selling complete will likely net more than parting out unless you have specific demand for the individual figures.

Seller notes

  • Sealed copies sell for $179.99 vs $70.95 used — a 154% premium. If you have this set new in sealed box (NISB), price it accordingly.
  • This is a vintage set (2008). Condition of the box and instructions significantly affects value. A complete set with original box and instructions can sell for well above the average.
