Just took my 2003 kia spectra in for service. I bought the car 6 months ago with 31,000 miles, it's now up to 37,000. Had hoped the selling dealer did the 30,000 mile service but I guess not as today I was told the transmission fluid is brown & therefore needs flushing. Also told the left outer cv boot needs replacing & all 4 tires supposedly have dry rot in bead area and need replacing as well. What is an average cost [incl labor] to replace the cv boot? Is $190 ridiculously high? They also recommended tranny service of $150 and $470 for 4 tires [not incl alignment]. I can easily shop around for better prices on 4 tires, I hope. But I'm at a loss about the transmission service & cv boot repair. Are they trying to screw me over? Should I replace the CV boot ASAP to prevent more costly future repairs? Thanks for all advice.
