How do I know a part will fit my BMW 4 Series?

Every car-specific part here is linked to the BMW 4 Series Convertible (G23) in our vehicle list, which records fitment by model, chassis and year. Universal items are shown too and suit most cars.

What is your returns policy?

You have 28 days from delivery to return a part: within that time, let us know and send it back to our warehouse. The full terms are in our refund policy.
Are parts covered by a guarantee?

Yes. Everything we sell carries a 6-month AUTOID guarantee, and many parts also carry the maker's own warranty, which varies by brand.

The G23 4 Series Convertible returns to a fabric roof, keeping the coupe's low, wide proportions. The right parts sharpen its character without losing what makes it good to live with.
