I purchased a GS350 Model: 2012 a few months ago which is now due for 45000 kms service. I found out that I can service it with a good reputated and accrediated mechanic for only $160 but am not sure whether they would have all the computer equipment for testing etc. How much would it cost me to do it with a Lexus dealer? Do they have a capped 45k service price? Is it okay to service it outside Lexus dealership and what is your recomendation?
