(Some re-painted surfaces differ slightly from the original paint). Installation of the smooth belly and wheel well liner significantly improved aerodynamics and the shape of the body. After all upgrades N231LG contains practically all features of the 252 model.
Exterior 8 out of 10. The only reason for not assessing it 10 out of 10 is the minor color difference in the some areas of the paint.

N231LG is upgraded to 252.

In 1985, Mooney's engineers were tasked with making as many improvements as possible to the 231 and bringing to the market a vastly improved airplane in 1986 - the M-20K 252TSE.  Among the improvements were improved engine cooling and a redesigned primary air induction system.  TCM made big improvements to the LB engine that resulted in the MB1 version. The changes were many.  Most important were a tuned induction system for more even induction airflow to the cylinders, a larger Garret turbocharger, a manifold pressure controlling system allowing full throttle operations for takeoff, and the incorporation of an intercooler that cooled induction air temperatures by as much as 100 degrees F.  The improvements resulted in the 252 that ran cooler than the 231, required only 36 inches of manifold pressure versus 40 with the 231, and flew 10 kts faster than the 231.
