Prior to 91 would be a second gear start, which I actually prefer. The higher number ratio is geared "lower", would be quicker off the line but use more fuel (other things equal). The reality is there aren't that many strong, well maintained cars of this vintage out there. I'd say find the best one you can and don't worry too much about what year it is, i.e. in the 88 to 92 timeframe.
