I am selling my Q45 that I have owned for 2 1/2 years. I have changed the oil regularly. I have also recently installed new front struts. Also inner and outer tie rod ends. I have installed Michelin MXV4 tires. The check engine light is on due to the driver side exhaust manifold. I must inform potential buyers of this issue to avoid being accused of being dishonest. The repair is not necessary but recommended. The manifold pictured is $249 and the under carriage assembly is $328. The driver side manifold is part# cc1855xl on macautoparts. net and the dual catalytic manifold assembly is part# REPI960307 on autopartswarehouse. com. Thanks for your interest. Happy Bidding!! NO RESERVE!
