- Not sure on the fuel pump. The correct way to check the pump's performance is to test the fuel pressure at the fuel rail on the engine.
- Determine if you have SLS (Self Leveling Suspension) first. If you do, you will be limited to OEM on the back. Unless you are looking to change the ride/performance I generally suggest OEM replacement. Have the suspension inspected. Many components use rubber bushings which wear with time regardless of mileage.
- Car was built for international license plates. There are probably adapter plates you can buy to mount US license plates in the center but not sure how well it looks. I think dealers may have something.

How much firmer are the HD´s ? Im thinking about replacing them since the ride does seem a bit bouncy and i dont remember being that way. Is the pierburg better than the bosch?
US cars are drilled for US license plates on the trunk. On the front there is an adapter.
drive it for a while and let the moving parts start moving again,before deciding what to replace. Fuel sitting for years in a fuel pump could easily gum it up and if it runs fine may just take a bit to quiet down.
Sachs boge are the oem shocks and those also probably just need to be used a bit before you decide shot or not.
Center the plate and drill new holes in the plate if wide enough or you will need to make your own adapter.
Time to change the spark plugs,time to change the trans fluid
Enjoy the new car

I put Bilstien HD on my car 4 years ago and they have been just fine.

You may be able to buy a bracket from the dealer. I've had them on my Euro spec SL's.

I did a full brake job, changed the fuel pump, drained the gas tank, cleaned injectors, ive been using a fuel system treatment, ordered a bracket from the mb dealer (thanks to a quick search on mb world i found the part number), ordered a oem e55 exhaust that i will be custom fitting to the car, ordered a set of practically new oem 18 inch monoblocks , installed k&n filter and new airbox since old one was missing some latches, ordered some nitto invos, new hood star since it was missing one, changed the oem shocks to bilstein touring shocks, did a tune up, Daily drove it for 2 days and then i left it at the paint shop to get the hood resprayed as well as the front bumper. Its coming along nicely ill post some pics when its out of paint.
Next on the list:
- New tail lights cant decide if i should go with oem clear tail lights or smoked e55 taillights. Will facelift tail lights work on my pre facelift e420?
- Polish my front headlights since they are a little yellow.
