This car had inspection 1 done about 3000 miles ago, and I would expect they look for the rear subframe then, so I'm not too worried there. I think its too little miles for RTAB as well.
The dealer told me to look at the seam to the outer side of the front strut tower mounts to see if there was any separation there. Apparently its common, but I havent heard about this on the forums yet. I guess you have to drop the motor to fix those welds, so its really pricey.
He also said to check the springs by running my hand under there to see if its cracked off. I guess the z4s have this issue as well.
Anything else to check while I'm there looking it over?!
It looks like a perfect car so far. Not a scratch on it!
