I have been driving a Lexus RX for the past 22 years and I am due for another one. Since they changed the engine from a six-cylinder to a 4 cylinder Turbo on their redesigned 2023 RX 350, I cannot get to used to the unbearable roaring engine noise. I am about to retire and I need to replace my 15-year-old RX 350 but concerned about the reliability of the GLC. I love everything about GLC, it is quieter than RX and really fast even with a 4-cylinder turbo engine without a turbo lag. I test-drove it and I truly love the GLC but I am worried about repair and maintenance costs. Does MB honor their extended warranty and normal warranty bumper to bumper without any hassle? Can you help me to figure out the maintenance cost and potential issues for the first five years? Do you think I will regret if go with an MB after enjoying good reliability with Lexus for the past 22 years? What I am reading online about MB ownership is scary and exciting same time. I am stuck with consumer reports removing GLC from their recommended list. Please help me make my decision. Thank you all.
