Daytona vs. Shadow

Ok here's the deal, this guy is gonna sell me his 91 dodge dayonta es (3.0 V6) for 400 while there's this mechanic with a 93? Shadow (2.5 L I4) selling for 500. Both of each have fading paint, etc. The daytona needs new exhaust gaskets, and water pump/timing belt (i already have both). The shadow needs nothing done to it (the mechanic has fixed everything wrong with it), but no A/C and i live in Arizona (hot hot hot). I am stuck between the two, which should i get.

i peronally would avoid the mitsubishi engine in the Daytona, but the shadow is mighty sluggish. If you can fix the daytona it would definitely be more fun, but the shadow should be more reliable
