The lower mileage one appears to be an automatic car - per picture. I am going to call up the dealership on Monday to see if it is a manual or automatic. Assuming they had the wrong pictures and it is a manual, which one would you go over? What maintenance needs to be done at around 58,000 miles beyond the oil & filter change?

Thanks,

Dave
