I am currently driving a 97 S320 Benz. It's a V6 which is fairly good on gas and the luxury options i have is more than enough. It's a comfortable ride and I feel safe in it. Due to the maintenance costs, I am considering to switch to a Cadillac which is V8. I don't do a lot of city driving but still it's a V8. It's a big and comfortable car and maintenance fairly will Chrysler wiTech MicroPod 2 be cheaper. I am not talking about oil changes, lets say if the transmission jerks or AC fails down or any small electronic issues.
