I was hoping the wisdom of CarTalk could help me figure out what the appropriate mileage (miles-per-gallon) for a '99 Mazda Miata with about 65,000 miles on it would be? I’ve been keeping track when I fill it up and saw that it was only getting 18-20 mpg with 75% city driving. Is that average for this car and this age? Or is this more of an indication that there is something off with the engine but not so ill-performing as to cause the check-engine light to come on.
Thanks for any insight.
p.s. What is up with the message board only allowing a choice between Mazda models 626 or 929?
