I have an '02 E39 M5, a soon to be '96 328ti, and a '86 E28 eta. The M5 could probably benefit from new sensors all around. The ti will need all new rubber bits from hoses, to bushings, to mounts, to tires. My son's eta needs everything, mainly a muffler though.
We would have to sit down and prioritize even with Tischer's great prices.
Thanks!
