1991 Mercedes-Benz 560SEL Reviews
This is a great car. Love its body style... presence but not over bearing Sleak stylish but elegant. Sophisticated but flamboyant. It has the "look".. no question... she is on the road... I am not a racer but I can get up and down the road. I have an issue coming up with the timing chain needing to be replaced... cost at the dealership is beyond the book value of the car.. after market foreign car tech will charge $800.00 installed with checking leakage and torgue and specs for that car.. hum!!! Sounds like I found the mechanic for this up coming repair.. OK nuff said... when working this is one of the best cars to drive for room and comfort.
