Is it expensive to replace a car starter motor & alternator?
not as expensive as you may think as they will take your old one as a trade in part exchange,,,they recondition it and sell it on,,,try a dealer first and then check if you have a local car electrics shop that does re conditioned stuff,,, if your car tho is 2002 vintage it is nowadays very unusual to to have an alternator fail,,,or even a starter motor check that your drive belt is not loose and slack and check electrical connections.
