I don't know how this bclark is, but don't believe that crap!! Here,s what happen to me, Debbie and I had an agreement for them to do a tune-up on my 2003 Expidistion for 300.00. they put 8 spark plugs in the motor and then called me to try an get another 149.50 more to put in a air filter and a gas filter. SO, they refused to do the tune-up after they put in the plugs. They went back on there word and only put the plugs in and charged me the 300.00 . DONT EVER GO TO THESE LIEING SCAM ARTISTS!!! PLEASE FIND SOMEONE ELSE!!!
