hey guys.. well i totaled the car in my pic

on a spin out on the high way.. im fine but the car wasnt.. ..i guess the good news is ive decided i loved it so much i want a 5.5 gen 6 speed.. im looking at a few and going to test drive one this sat... i was wondering if you guys could give me some avice on what to be aware of and what to look for.. if it was a 5th gen i would know everything.. coils maf cat all the commons.. well..i know about the burning oil but is there a way to find that out? ..also on the 6 speeds.. how do u know if it has the HLSD? Also.. (i already KBB and NADA'd it) lets say i found a 5.5 6speed loaded everything but nav with only 19K orig miles on it drivin by an older man who just went down the road and to the golf course.. would i be crazy to be interested in it if it was in the 14.5 K range? thanks for the help guys.. i appreciate all the past help and would rather get a 5.5gen then some other crap.. thanks
