looking at getting a supra

[racin66coupe]

ive been looking at getting a supra for a bit now, and i have found a few that catch my eye, ive decided i need one with atleast a sunroof if not the targa top, so ive found 2 for about my price range, around 2k. both have about 150k on them, but have had maintenace done, timing etc etc. both 5 speeds, just one of them is a turbo, and one isnt. what is the difference in power between the two? is there anything that i should be looking out for? unfortunatly one of them has a blue interior which i hate but if i bought it i would most likely change it over to black and then paint the car.
so my questions are, what should i be looking out for? and whats the performance difference between the turbo setup and the N/A setup?
the turbo is a 87 and the n/a is a 88
