i have just gotten a 1992 nissan nx 1600, it has minor scratches and has 148000 miles. i was wondering if that was too many miles? and also if any one knows anything about the cars engine and if its even worth kereping.

you have a 1.6 liter named the GA16DE. It's a super reliable engine with a smooth torque curve. With proper care it should last you past 300k. Not much power, but great gas mileage. There are mods available, but don't expect too much power out of it. The car's worth keeping if you need a economical daily driver.
