I've taken my 2000 Boxster S to Mikar (
https://www.yelp.com/biz/mikar-carmel) in downtown Carmel because it's a few blocks away from where I work. They frequently have Ferraris and Lamborghinis in there, so I figured they'd be safe to trust my 986 to. Guys are very friendly and no B.S.
A friend of mine with a 911 and Cayenne takes his to Euro Motorworks in Fishers (close to I-69 just south of 96th St.).
