After driving a certifiable lemon, I purchased the Altima. The ride is really smooth. I haven't needed any major repairs to the car, just annual stuff and oil changes. The heat/air cond. is superior. The seats are comfortable. Gas mileage is good. The trunk is roomy also.
Defrost! It kicks in quickly and it hasn't failed me yet. CD player - gets me through long road trips Brakes - crazy drivers on the road.
Replace the frame of my car with a Jag frame. (My dream car.) This car doesn't need improvements, just someone who takes care of their car and it will take you wherever you need to go.
