im thinking of buying an impreza 94 to replace my aging xt turbo. i found one in town here for 3 grand. it looks like it has an oil leak that looks like it is coming from the oil pan. what else should i look at while im am at it?

Get it on a lift and look everything over. CV boots, diff seals, gearbox seals, are the chassis bits straight and not rusted through...11 years old, needs careful scrutiny.
