I really enjoy a well done engine swap. Three months ago I featured a W113 Pagoda with a M104 3.2 inline-6 swap. Today’s car is another M104 swap but with a little more displacement and a lot more AMG. What started out as a nice W124 E320 wagon was transformed to a hybrid C36/500E/E320 borrowing various parts from both cars. It’s a unique build that I haven’t seen and sure is an improvement over what Mercedes offered from the factory. So let’s take a closer look at this uber W124 wagon for sale in Connecticut.
CLICK FOR DETAILS: 1995 Mercedes-Benz E320 Wagon 3.6 AMG on eBay

The basics: 1995 E320 wagon with C36 AMG engine swap. 202,000 miles on the chassis, midnight blue over black, ASR, heated seats, replacement wiring harness & throttle body, Cold AC, rebuilt and upgraded suspension all around, fresh brakes all around.
The wagon has much of the appeal of the 500e, but has the extra utility of a wagon. Regular body w124 cars spare body parts are far less pricey and much more common than a 500e. The midnight blue paint is original and has normal wear expected from a 21 year old driver quality car. I have a porter cable buffer and have used it to the best of my ability on the paint. The black interior looks outstanding with the burl wood trim, 500e heated front seats, and 500e steering wheel. All of the leather has been treated with leatherique.
The car’s exhaust is not running any cats at the moment, but will come with an extra set of factory catted pipes. It has a current CT emissions and has never had any issue passing. I have replaced the heavy Mercedes factory resonator for a more performance oriented piece. The exhaust has slightly more sound than stock, but it is still pretty quiet. The top end is noticeably improved with this set up. The non cat 3.2 m104 was good for around 20 hp more than the catted USA version so the engine should be putting out close to 300 horse power as is.
The suspension on the car is on point and the ride quality is superb. The self leveling system works 100%. In my opinion, the car drives best on the light weight CLK wheels. Everything on the front and rear suspension is new and has been upgraded to 500e or Mercedes sportline spec. The car handles like a much smaller car and stays planted during any sort of spirited driving.
The car has the stock 2.65 gearing so it takes a good stab of the gas pedal to get it moving. The 3.6 engine comes life above 3500 rpm and has a very strong top end compared to a 500e. The engine is reminiscent of a 190e 16v. It is possible to mate this engine to a manual transmission. I have a line on a 3.06 ASR differential which would really transform the car off the line.
Many, many hours have (and $) been spent bringing the car up to where it is at now. I have a giant stack of receipts for all the work that I have done and by the previous owner. It has taken the better part of five years to get to where it is now. I wouldn’t have been able to do any of this without the help out w124 guru David Hendy who’s eBay store is Blitzen Motorsports.
The car does not have any mechanical needs and just needs a new owner. I am confident that the first person that drives this car will buy it. These cars have a very special feel that exudes quality and this one delivers that feeling in spades.

Taking a look at the long list of modifications and changes in this wagon, you can see this wasn’t a quick weekend swap. Everything looks well planned out and I’m having a tough time spotting anything that doesn’t look OEM. The 3.6 litre M104 from AMG isn’t the biggest power marker in the world, but 275-ish horsepower is enough for this car. Inside the car, the interior was completely swapped out from the original caramel colored leather to 500E seats and steering wheel.
It’s really tough to put a value on cars like this. The sum of all the parts replaced and swapped in probably exceeds the $10,000 price tag for this car. The body having over 200,000 mils on it with some iffy paint on the hood as well as some rust starting to bubble on the front fender isn’t ideal, but that can be fixed without much issue. The key here is that all this work looks like Mercedes did it themselves and there are no outstanding issues that you need to button up. If you love the W124 wagon, which a lot of people do, then I could see someone justifying the $10,000 it would take to buy this car.
The gentleman who did this car spent a lot of time and effort ensuring it was done correctly. He’s not lying when he says there’s five years in it. Just on time and hair-pulling-out, there’s way more than 10K spent. If I had spare cash I’d buy this car in a heartbeat. I had a first-year M104 powered 300TE and it was a fantastic car on the highway. It had some scoot in the upper rev range, so I can only imagine what the AMG engine is capable of.
My mom had a W124 diesel wagon back in the 80s. What an amazing car, especially on the highway. Not at all fast but once up to speed, the diesel was a very flexible engine. This 3.6 AMG I6 sounds like the best compromise for the W124. While not quite having the power and torque of the 500e, it is more than enough to move this heavy wagon with some authority. I like everything about this wagon except for the miles and rust. If the body paint were better and it had 100k miles I would be a buyer at 10k (it’s even 20 miles from my house!). As it sits I think the seller is going to need to be pretty flexible on his price if he wants to sell it.
