I would imagine this question has been asked numerous times, new user, but would like some "expert" opinions. In February, bought 1999 Boxster 986, 5speed with 74k miles, like new, drives great engine feels very strong no slippage, had Rennsport Porsche Works here in Sealy, TX give it a good "once over", replaced oil, filter, etc. said no major issues they see - Car now has 76k miles on it. Their opinion on IMS issue was replace oil / filter every 5,000miles, drive the car "like you stole it" don't worry about it.
I spoke to another shop in town about "performance" upgrades to the car, exhaust, etc. the first thing they asked "have you replaced the IMS"??? Gave me the scare tactic about dropping the transmission and really see what is going on if anything before talking performance upgrades. As you would expect with a 99 boxster, not an expensive car, but love it and would hate to "lose it" - what should I do? appreciate any feedback
