My 300sdl (big baby) is stuck in 2nd gear. the repair guy said it would cost around $3500 to fix. i only paid $2500 for the car and i really can't go from benz to just anything. would it be wise to just trade or sell the car instead of paying for it to be fixed? i've never trade a car before. if i do how much should i be asking? also is this a problem i may be able to fix myself?
