Slipping or not

[IS250IS250]

Hi all 

I recently purchased my 2nd IS250 and love the car to death.

Only had it 5 weeks. 

Performance and comfort. It felt like old model performance wise.

But now I am not sure. There might be a small slip or drop in performance. I don't know if I am over paranoid or it is just bad luck week's in. Furthermore sometimes I hear a blowing of the exhaust but it sounds more like cardboard in bicycle spokes. But can only hear in built up areas where noise rebounds. 

Any advice?

 

Trip to the garage?

Hi Paul. What kind of service history has the car got? Maybe book it in with your nearest Lexus dealer for a service. At least they take a good look at the cars. How many miles on it?
