Find yourself a 325i or 325is. The 325es has the 2.7L engine but its an ETA engine which was intended to be the gas saving wonder. In reality, it doesn't get the MPG of the 2.5L and definetly doesn't have the punch. It also has WAY to many sensors and keeping it tuned can be a pain. If the 87 325es is garage kept and pristine I'd offer $1200 and hope that they decline so you find an 325i or 325is but I've seen many SD for $1000 to $1200 range.
