Interior Resurrection: Restoring the E38 740i Cabin

The Starting Point

The interior was rough. Not destroyed, but definitely showing its age in ways that made the car feel neglected rather than cherished.

The headliner was drooping, which is basically an E38 rite of passage. Every single one of these cars eventually develops headliner sag. The A, B, and C pillars had the same tired fabric. Front seats were worn in the usual spots. The whole cabin just felt like a car that had been sat in for two decades.

I could have just lived with it. Plenty of people do. But if the goal is OEM-plus, the interior has to match the exterior and mechanical improvements. No point having perfect paint and suspension if you're sitting in a saggy, worn cabin.

Alcantara Transformation

Rather than just replacing the headliner fabric with matching material, we went with Alcantara throughout. This was a chance to upgrade the interior's feel while solving the practical problem.

Components redone in Alcantara:

• Headliner, the main event

• A pillars

• B pillars

• C pillars

• Interior mirrors

• Sunroof shade

• Sun visors

• Rear deck lid

The Alcantara creates a cohesive, premium feel throughout the upper cabin. It's a material that ages better than the original fabric and has a more luxurious hand feel. When you get in the car now, it feels special in a way the worn original interior never did.

Front Seat Restoration

The front seats were shipped out for proper restoration. We're talking complete reupholstery with new leather skins, not just some conditioner and hope.

The bolsters had the typical wear from 24 years of entry and exit. The seating surfaces were compressed and shiny in spots. These seats needed more than cleaning, they needed rebuilding.

I got them back nice and tight. The difference is immediately obvious when you sit down. Proper support andfeel, no more sliding around on worn leather. They look and feel like new seats now.

The rear seats were in better shape since they see less use. Pulled them out for thorough cleaning and conditioning with Nanolex Professional Interior Cleaner and extraction. Deep cleaning made a significant difference without requiring full reupholstery.

Steering Wheel Refinishing

The OEM Sport steering wheel was the right piece for this car, just worn from years of use. Rather than replacing it with something aftermarket, we had it refinished.

This approach maintains the classic  look and feel while eliminating the wear. The grip is restored, the leather is fresh, but it's still the proper E38 steering wheel. Original, just renewed.

Sourcing NLA Parts

Some interior parts are getting impossible to find. When you come across them new, you grab them.

B Pillars: The original B pillars were damaged, buckling in that way old plastic trim does. I was lucky to find brand new OEM ones still in stock. Other colors were already NLA, but black was still available when I ordered. That window is closing fast on these parts.

Floor Mats: The beat up old floor mats got swapped for new. Fronts were still available as a new OEM. Rears are NLA, so those had to be sourced as new old stock. Not easy to find, but worth the effort.

This is the reality of restoring a car this age. It's a race against parts availability. Things that are available today might not be available next year. Buy it when you find it.

Detail Upgrades

A bunch of smaller changes added up to transform the interior feel.

Shift Knob: I removed the wood shift knob and replaced it with an all-leather OEM version. The wood looked dated in this interior. The leather knob suits the car better and feels nice in your hand.

Center Dash Grille: The original was cracked, which happens on every E38 eventually. It was replaced with a new OEM piece. Small detail, but you look at that part of the dash constantly.

Armrest Phone Carrier: The original phone carrier in the armrest was useless, just a reminder of early 2000s mobile technology. I replaced it with the OEM coin holder instead so it's actually functional now.

Rendition Cup Holder: I swapped out the old OEM ash tray for a Rendition cup holder with USB charging ports. A modern convenience that integrates cleanly. You get cup holders and charging without some janky aftermarket solution.

Wood Trim: I polished out the wood trim with a Rupes iBrid and Rupes Fine Polish. The wood was hazed and dull from age and UV exposure. It brought back the depth and gloss without replacing anything.

Rear Sun Shades

The rear sun shades were shot. These electric shades are an E38 feature that rarely works properly after two decades. I got them replaced so they actually function again.

It's one of those things that makes the car feel complete. The E38 was a technology showcase when new. Having the features actually work really augments  the ownership experience.

Putting It Back Together

Interior restoration means taking a lot of stuff apart. Every piece has to go back correctly or you end up with rattles, gaps, and pieces that don't quite fit.

Took our time on reassembly. All the Alcantara pieces needed to align properly. The seats had to be reinstalled and adjusted. Trim pieces clicked back into place. The whole process is satisfying when it comes together.

The result is an interior that looks and feels better than it did when the car was new. The Alcantara headliner is nicer than the original fabric. The reupholstered seats are tighter than factory. The details are all fresh and correct.

What This Delivers

You spend all your time in the interior. The exterior gets compliments from strangers, but you experience the cabin every single drive.

Getting in the car now feels like an event rather than an obligation. The Alcantara headliner, the fresh seats, the thoughtful details everywhere you look. It's the E38 experience as it should be, not the worn-out version most of these cars have become.

This is what sets a considerate restoration apart from just keeping a car running. Anyone can drive an E38 with a saggy headliner and worn seats. Building one that feels special takes work and investment. The interior restoration was a big part of making this car something worth preserving.
