Pretty good deal.
She's staying. Unless the right 135i came along at the right price, which won't happen.
I'm still probably going to add some spacers to the rear and do some other little things here and there. I just can't improve upon the stock things enough to justify modding it much. Especially compared to the Miata.
OEM GTI Suspension is pretty damn stiff. I can't really improve on the balance for a daily driver with any coil under $2k, so it's just not really worth it. $2k towards the Miata could be an LS1 swap, way worth it.
