I bought a new Honda in 1990. I just now passed it on to my son, and bought a two year old Toyota.
Think of all those cars that didn't get built because I drove the same car for 25 years. I thought about that often.
The only time it didn't pass emissions test is the gas cap didn't seal properly. Bought a five dollar cap and was good to go.
And it gets 35 mph in daily commuting.
