Some tips for you all.
Many may have seen, but some may not have.
Most glaring thing.........................
Look how clean the brake fluid is?
Is that a car that was treated like a washing machine or a toaster?
Then look at the shocks and actuators...................
They do not look that nice on an unkempt car.
Sometimes it is pretty easy to spot a POS or a potentially very good car.
Now, could be recent smart maintenance, but on a ZR-1 it is usually pride of ownership.!
Nice ZR-1!
