Strong result @seller - I am so curious, as an SEC owner preparing for engine/trans swap, about pricing (what you have into it pre-swap, cost of swap, etc.) - I would be so thankful if you sent me a DM on BenzWorld, (same username) so that I can pick your brain and swap stories.December 22nd, 2025 at 4:30pm EST$59,000 bid placed by @HumbleFarmerDecember 22nd, 2025 at 4:29pm EST$58,000 bid placed by @MrNobodyDecember 22nd, 2025 at 4:28pm EST$57,000 bid placed by @HumbleFarmerDecember 22nd, 2025 at 4:27pm EST$56,000 bid placed by @MrNobodyDecember 22nd, 2025 at 4:26pm EST$54,000 bid placed by @HumbleFarmerDecember 22nd, 2025 at 4:25pm EST$52,500 bid placed by @MrNobodyDecember 22nd, 2025 at 4:23pm EST$50,000 bid placed by @USI_CarsDecember 22nd, 2025 at 4:23pm EST$46,000 bid placed by @HumbleFarmerDecember 22nd, 2025 at 4:22pm EST$45,000 bid placed by @BeckermachineDecember 22nd, 2025 at 4:21pm EST$44,000 bid placed by @HumbleFarmerDecember 22nd, 2025 at 4:19pm EST$40,000 bid placed by @BeckermachineDecember 22nd, 2025 at 4:13pm EST$39,000 bid placed by @HumbleFarmerDecember 22nd, 2025 at 4:04pm EST$37,500 bid placed by @USI_CarsDecember 22nd, 2025 at 4:01pm ESTV_for_Jackhammer (15) Seller 1@ClayMan Open diff. But can replace it with LSD if buyer chooses soDecember 22nd, 2025 at 4:01pm EST$35,000 bid placed by @MrNobodyDecember 22nd, 2025 at 3:58pm ESTClayMan (2) 1Is the 2.47 an open diff or LSD?December 22nd, 2025 at 3:52pm ESTV_for_Jackhammer (15) Seller 1@ClayMan Difficult to say, cluster was innoperational when we got it. Engine/gearbox was chosen based on the best overall condition, so again mileage unknown. Either way, most wear items were replaced on all of these, so it shouldn't have issues any time soonDecember 22nd, 2025 at 3:36pm ESTClayMan (2) 1What is the mileage of the motor / transmission and chassis? According to the CarFax it was last recorded at 169K-miles in 2009.December 22nd, 2025 at 2:38pm EST$30,000 bid placed by @AUS_BenzDecember 19th, 2025 at 3:37pm EST$26,000 bid placed by @BeckermachineDecember 19th, 2025 at 4:36am ESTV_for_Jackhammer (15) Seller 1@DoctorEurocar The NA version is definitely much easier to swap, plus you don't need as strong clutch/gearbox/driveshaft etcDecember 19th, 2025 at 4:34am ESTV_for_Jackhammer (15) Seller 1@Pmarsico9 Sure does, tho not as cold as with OE R12 system. Thanks to all others for wonderful comments!December 19th, 2025 at 12:07am ESTquantumorbit (11) 1This restomod is sickDecember 18th, 2025 at 6:38pm ESTDoctorEurocar (2) 1This Is incredible build. I am powering all my classics with 5.4 AMG NA motors and 6 speeds...Buying up slk320/6 speed and crossfires....Looking at this gives me motivation to start my w124 5.4/6 speed swap in 2026 if God spares. Great build, Whoever buys will get one of Mercedes Best looking coupes with their best v8 engine.December 18th, 2025 at 1:51pm ESTbigjay850 (0) 0@V_for_Jackhammer great work on the car, looks very cool (except the color, but that's a taste thing) I do see that you've added AMG front and back US bumper skirts (lip, apron), any help to fellow enthusiast as where to source those from? Thank you and good luck with your sale!December 18th, 2025 at 12:42pm ESTPmarsico9 (1) 0Does the AC blow cold?

Can you give any advice on making this conversion?December 15th, 2025 at 7:22pm ESTAtatexan (4) 1Some people are hung up about originality. I got Some grief for what I did to make my Euro W116 350SE a better more usable car. Nothing as incredibly cool as this car but recaro front seats, H&R springs, R134 AC conversion with rotary compressor and special fan slaved to the compressor switch. Guess what the car never overheated on brisk Texas summer road trip. This car will last forever mechanically and looks original. I admire It a lot. The new owner will be very lucky.December 15th, 2025 at 1:11pm ESTGoBoGo (102) 1This Is So (expletive) Cool.... GLWTA!!!December 15th, 2025 at 12:42pm EST$20,000 bid placed by @pillesteinDecember 15th, 2025 at 10:14am ESTantonvt (4) 0Thank you for feedback.December 15th, 2025 at 8:27am ESTV_for_Jackhammer (15) Seller 1@antonvt Dear potential buyer, This radiator is only 5% smaller than the stock CLS/E55 kompressor one. Plus has split cooling for intercooler, oil cooler, and powerful ECU PWM controlled fan. So there are no overheating issues. Car was driven during this summer to confirm all is good.December 15th, 2025 at 5:52am ESTantonvt (4) 0Dear seller, thank you for feedback. I have a question: did you make any research/math into the cooling of the engine? If I’m not mistaken I see the old 126 radiator, but M117 does need much more cooling…December 15th, 2025 at 5:45am ESTV_for_Jackhammer (15) Seller 0@antonvt 2 sets of keysDecember 15th, 2025 at 5:44am ESTV_for_Jackhammer (15) Seller 0@DanS Old parts are not part of the deal, but if the buyer wishes old engine/gearbox instead of M113k, I will swap it back. I don't know about regulations in R
